Predictors of asthma control in children from different ethnic origins living in Amsterdam.

To identify factors associated with asthma control in a multi-ethnic paediatric population. We interviewed 278 children with paediatrician diagnosed asthma (aged 7-17 years) and one of their parents. Asthma control was assessed with the Asthma Control Questionnaire (ACQ). Detailed information about sociodemographic variables, asthma medication, knowledge of asthma, inhalation technique and environmental factors were collected. Turkish and Moroccan parents were interviewed in their language of choice. Logistic regression analyses were used to identify correlates of asthma control. Of the 278 children, 85 (30.6%) were Dutch, 84 (30.2%) were Moroccan, 58 (20.9%) were Turkish and 51 (18.3%) were Surinamese. Overall, almost 60% had a status of well-controlled asthma, as indicated by the ACQ. Only 51 of the 142 (35.9%) Moroccan and Turkish parents had a good comprehension of the Dutch language. In logistic regression analyses the risk of having uncontrolled asthma was significantly higher among Surinamese children (OR 2.3; 95% CI 1.06-4.83), respondents with insufficient comprehension of the Dutch language (OR 2.3; 95% CI 1.08-4.78), children using woollen blankets (OR 9.8; 95% CI 1.52-63.42), and significantly lower among male (OR 0.5; 95% CI 0.31-0.91) and non-daily users of inhaled corticosteroids (OR 0.6; 95% CI 0.38-1.07). In conclusion, ethnicity as well as insufficient comprehension of the Dutch language appeared to be independent risk factors for uncontrolled asthma. Special attention should be given to children from immigrants groups for example by calling in an interpreter by physicians when comprehension is insufficient.

Factors associated with hypertension awareness, treatment and control among ethnic groups in Amsterdam, the Netherlands: the SUNSET study.

We sought to determine factors associated with hypertension awareness, pharmacological treatment and control among ethnic groups in Amsterdam, The Netherlands. We analysed data on hypertensive subjects (Dutch n=130, Hindustani n=115 and African Surinamese n=225). After adjustments for important covariates, hypertension awareness was more common in Dutch people with abdominal obesity and family history of hypertension (FHH). Abdominal obesity was also associated with higher level of awareness in African Surinamese. Female sex, FHH and recent physician (general practitioner (GP)) visit were associated with higher level of awareness in both African and Hindustani Surinamese. Among the Dutch, hypertension treatment was more common in those with abdominal obesity, FHH and GP visit. Among Hindustanis, female sex, abdominal obesity and GP visit were positively associated with treatment of hypertension. Old age, female sex, FHH and GP visit were positively associated, whereas smoking was negatively associated with lower treatment in African Surinamese. High education and more physical activity were associated with better blood pressure (BP) control, whereas obesity was associated with poor BP control among the Dutch. Among African Surinamese, female sex and FHH were associated with better BP control, whereas abdominal obesity was associated with poor BP control. Only old age was associated with poor BP control in Hindustanis. In conclusion, our findings indicate that more attention is needed in promoting awareness and treatment among those with lower hypertension risk (i.e., normal body weight people and those without FHH), those without recent GP visits in all ethnic groups and African and Hindustani Surinamese men and smokers. More effort is also needed in hypertension control among Dutch people with low education, obesity and inadequate physical activity, African Surinamese men and those without FHH and old Hindustani people.

Acculturation and education level in relation to quality of the diet: a study of Surinamese South Asian and Afro-Caribbean residents of the Netherlands.

BACKGROUND: To consider the changes in overall diet quality following migration we examined the associations of acculturation variables and education level with diet in Surinamese South Asian and Surinamese Afro-Caribbean origin on the one hand, and ethnic Dutch residents of the Netherlands on the other. Surinam is a former Dutch colony in South America. METHODS: We randomly selected men and women aged 35-60 years: ethnic Dutch, n = 552; South Asian, n = 306; Afro-Caribbean, n = 660. Intakes of fruit, vegetables, red meat, fish, vegetable oils, breakfast and salt were measured using a short questionnaire that formed the basis for a 'diet quality indicator' score. Highest education was measured and acculturation of the Surinamese groups was assessed by age at migration, number of resident years and a scale measure of social contacts with ethnic Dutch. RESULTS: Compared with ethnic Dutch, both Surinamese groups scored higher on overall diet quality (P < or = 0.001) but some aspects of diet (breakfast and salt use) were less prudent. Education was positively associated with diet quality in ethnic Dutch (P < or = 0.01), but not consistently so in Surinamese. Associations with social contact with ethnic Dutch varied for different quality aspects of the diet. Residence duration (mean = 22 years) and age at migration (mean = 21 years) were not associated with diet. CONCLUSIONS: A greater degree of acculturation does not necessarily lead to a less healthful diet in migrants. In addition, the association of education level with diet may differ for migrant groups. The diet of migrants differ from host populations, suggesting that migrant groups should be considered in the development of nutrition health promotion activities.

[Cardiovascular risk factors for Surinamese in the Netherlands: a literature review].

OBJECTIVE: To obtain an overview of the prevalence of cardiovascular risk factors in Surinamese (Hindustani and Creoles) individuals in the Netherlands and the implications of this for secondary prevention. DESIGN: Literature study. METHOD: A Medline literature search was carried out for the period 1985-2001 with the keywords 'cardiovascular risk factor' or 'cardiovascular risk factors', and 'Surinamese'. In addition to this, so-called grey literature was searched and the reference lists of articles found were also checked. A total of 7 studies were selected. RESULTS: Smoking is less frequent among Surinamese individuals in the Netherlands compared to the indigenous population, especially in women. The prevalence of both hypertension and diabetes is higher among the Surinamese. Data on dyslipidaemia are almost absent; it is only known that hypercholesterolaemia is less prevalent among the Surinamese. Ethnicity is not included in the risk cards used in the secondary treatment of cardiovascular diseases. CONCLUSION: The lack of research with respect to the cardiovascular risk profile of Surinamese (Hindustani and Creoles) in the Netherlands indicates an unfavourable profile compared to the indigenous Dutch population. This difference justifies further research into the differentiation of prevention and treatment according to ethnic origin.

The validity of self-reported use of health care across socioeconomic strata: a comparison of survey and registration data.

BACKGROUND: Socioeconomic differences in health and in use of health care are well known. Most data on socioeconomic differences in health care utilization are based on retrospective self-report in community surveys, but the evidence on the validity of self-reported utilization of health care across socioeconomic groups is limited. The aim of this study was to assess the validity of self-reported utilization of health care across socioeconomic groups in the general population. METHODS: We compared the concordance of self-reported and registered hospitalization (one year, n = 1277), and utilization of physiotherapy (one year, n = 1302) and use of prescription drugs (3 months, n = 899), by socioeconomic group (educational level, income, occupational status). Data came from a face-to-face health interview survey in Amsterdam and a health insurance register, and were limited to native Dutch and lower and middle income groups. RESULTS: Concordance between reported and registered utilization was generally good to excellent; kappas (agreement adjusted for chance agreement) and percentage accurately reporting ranged from 0.60 and 80% (drugs) to 0.80 and 96% (hospitalization). They differed little, and without statistical significance, between people of low socioeconomic status and others. Assessment of socioeconomic groups in more detail yields somewhat more variation, but no systematic trend in concordance by higher socioeconomic status. CONCLUSION: Self-report offers a reasonably valid estimate of differences in utilization of health care between socioeconomic groups in the general population, at least for lower and middle income groups.

Indicators without a cause. Reflections on the development and use of indicators in health care from a public health perspective.

Indicators have a long history in public health. Since the end of the 18th century information on the health of communities has been gathered on a health system level and public health indicators have become more sophisticated over the vears. However, in many modern health care systems there is a separation between public health and health services. This paper discusses the need for integration and promotes a stronger public health orientation of health services. This has consequences for the nature of indicators on the health services level. The methodological problems of turning epidemiological data into management information for health services are discussed. The key message is that the health of the community should be the ultimate cause of all indicators.

Immigrants in the Netherlands: equal access for equal needs?

OBJECTIVE: This paper examines whether equal utilisation of health care services for first generation immigrant groups has been achieved in the Netherlands. DESIGN: Survey data were linked to an insurance register concerning people aged 16-64. Ethnic differences in the use of a broad range of health care services were examined in this group, with and without adjustment for health status and socioeconomic status, using logistic regression. SETTING: Publicly insured population in Amsterdam, the Netherlands. PARTICIPANTS: 1422 people from the indigenous population, and 378 people from the four largest immigrant groups in the Netherlands-that is, the Surinamese, the Netherlands Antilleans, and the Turkish and Moroccan. MAIN OUTCOME MEASURES: General practitioner service use (past two months), prescription drug use (past three months), outpatient specialist contact (past two months), hospital admission (past year), physiotherapist contact (past two months) and contact with other paramedics (past year). MAIN RESULTS: Ethnicity was found to be associated with the use of health care after controlling for health status as an indicator for need. The use of general practitioner care and the use of prescribed drugs was increased among people from Surinam, Turkey and Morocco as compared with the indigenous population. Compared with the indigenous group with corresponding health status, the use of all other more specialised services was relatively low among Turkish and Moroccan people. Among the Surinamese population, the use of more specialised care was highly similar to that found in the Dutch population after differences in need were controlled for. Among people from the Netherlands Antilles, we observed a relatively high use of hospital services in combination with underuse of general practitioner services. The lower socioeconomic status of immigrant groups explained most of the increased use of the general practitioner and prescribed drugs, but could not account for the lower use of the more specialised services. CONCLUSIONS: The results indicate that the utilisation of more specialised health care is lower for immigrant groups in the Netherlands, particularly for Turkish and Moroccan people and to a lesser extent, people from the Netherlands Antilles. Although underuse of more specialised services is also present among the lower socioeconomic groups in the Netherlands, the analyses indicate that this only partly explains the lower utilisation of these services among immigrant groups. This suggests that ethnic background in itself may account for patterns of consumption, potentially because of limited access.

[Moroccans' opinions about general practitioners: analyzing reasons for consultation].

OBJECTIVE: To determine whether there is a difference in the extent to which the GP succeeds in establishing the reasons for consultation of Moroccans and those of the Dutch; and whether the opinion of Moroccans about the GP's consultation differs from that of the Dutch. DESIGN: Analysis of patient interviews and GP's consultations. METHOD: In 11 general practices in Amsterdam and The Hague in May 1997, 50 Moroccan adults and 50 Dutch individuals were asked for their reasons to attend before the consultation and in the mother language; a distinction was made between the actual complaint and the expectations with regard to the consultation. The GPs recorded these data after every consultation. The complaints were coded by organ system and by nature of complaint, following which agreement of the assessments was scored on a scale ranging from 0 to 100. RESULTS: Both groups comprised 20 men and 30 women. The mean age of the Moroccans was 38.6 years (SD: 13.8), that of the Dutch 56.4 years (SD: 16.7). The GPs established complaints of Moroccan patients not as well as those of Dutch patients (score: 73.9 versus 87.3); the difference was more pronounced where patients with only elementary education were concerned (67.0 as against 86.1). The GPs were able to establish the expectations with regard to the consultation nearly as often for the Moroccan as for the Dutch patients (58.5 versus 55.9). Moreover, the Moroccans were as positive about the course of the consultation as the Dutch. Except for communication problems among the lower educated, none of the problems indicated appeared to be experienced more often by the Moroccans than by the Dutch. CONCLUSION: A large part of the complaints presented by lower educated Moroccan patients were interpreted differently by the GP. For Moroccans with a higher education, the care was comparable with that among the Dutch.

Educational differences in excessive alcohol consumption: the role of psychosocial and material stressors.

BACKGROUND: Socioeconomic differences in health are determined mainly by socioeconomic differences in unhealthy behavior. Little is known, however, about the mechanisms that account for socioeconomic differences in unhealthy behavior, such as excessive alcohol consumption. In this paper we examined educational differences in excessive alcohol consumption in The Netherlands and whether these may be explained by educational differences in experienced stress and stress-moderating factors. METHODS: Data were obtained from the baseline survey of the Longitudinal Study on Socio Economic Health Differences in 1991. Excessive drinking was defined as drinking more than six glasses on 3 or more days a week or more than four glasses on 5 or more days a week. Socioeconomic status was indicated by educational level. Stressors were divided into psychosocial and material factors. Analyses were performed for women (n = 756) and men (n = 1,006) separately, among drinkers only. RESULTS: Excessive alcohol consumption was more common among lower educational groups. Material stressors, such as financial problems, deprivation, and income, were related to part of the educational gradient in excessive alcohol consumption. Differences in stress-moderating factors were not related to the educational gradient in excessive drinking. CONCLUSIONS: Our results suggest that improvement of material conditions among the lower educational groups could result in a reduction of socioeconomic differences in excessive alcohol consumption.

The influence of adult ill health on occupational class mobility and mobility out of and into employment in the The Netherlands.

In the debate about the explanation of socio-economic health inequalities one of the important issues is the relative importance of health selection. The aim of this study was to investigate to what extent occupational class mobility and mobility out of and into employment are health-related, and in addition, to estimate the contribution of health-related social mobility to socio-economic health differences in the working population. Data were taken from the Longitudinal Study on Socio-Economic Health Differences in the Netherlands, which started in 1991; follow-up data were collected in 1995. The analysis is based on 2533 persons aged 15-59 at baseline. The influence of health problems in 1991 (perceived general health, health complaints and chronic conditions) on changes in occupational class between 1991 and 1995 was negligible. Neither upward nor downward mobility was affected by health problems. However, health problems in 1991 were significantly associated with a higher risk of mobility out of employment and a lower risk of mobility into employment in 1995. For example, for mobility out of employment among persons that reported at least one chronic condition in 1991, the odds ratio was 1.46. Health-related mobility out of employment substantially influences the estimate of socio-economic health inequalities in the working population (measured by current occupation). For manual workers, as compared to non-manual workers, the odds ratio for a less-than-good perceived general health was underestimated by 34% in 1995. Selective mobility into employment overestimates socio-economic inequalities in health in the working population by 9%. Respondents that moved into and out of employment were healthier than those that remained economically inactive, but their health was worse than of those that remained employed (both manual and non-manual). Implications for health policy are that the prospects for people with health problems to stay in paid employment should be improved.

Inequalities in health--future threats to equity.

In discussions about equity there is a tendency to focus on the inequalities in health status that appear to be the result of the material and immaterial consequences of a lower income, professional or social status in society. If we look at publications such as the Black Report in the UK or Ongelijke gezondheid in The Netherlands, we have to accept that despite our universal access to healthcare and the existence in many Western countries of social security measures that preclude 'real' poverty, considerable differences in health continue to exist between socioeconomic groups. This is corroborated for many other European countries in the research carried out by a concerted action led by Mackenbach. These inequalities in health have been referred to in many countries as inequities, meaning that society finds them unjust and expects them to be 'avoidable' or amenable to policy interventions. However, the research on the causal networks underlying the occurrence and the avoidability of inequalities in health remains sparse and intervention studies seem to focus on policy measures that can be evaluated, but which will most likely have a limited impact on the inequalities measured at the population level. Thus the research community leaves policymakers with very little evidence on which to build policy initiatives that are nevertheless requested by many governments. The third element, which needs to be addressed in this context, is the ominous inequality in access to healthcare. Since the debate on equity in health has rightly been initiated in the context of a broader, more intersectoral approach to health policy, very little attention has been paid, so far, to the issue of universal access to quality healthcare services. This is because in the second half of this century most Western (European) countries have created a healthcare system with universal access, financed either through taxation or through social insurance schemes. It is these financing systems that will be threatened in the years to come by the considerable demographic shift occasioned by the ageing of the post-war baby boom and the incentives for risk selection that have been introduced in many systems as part of the 'market' mechanisms. The benefits of these incentives have clearly been a greater efficiency at the patient or service level, but there is still the question of whether it will be a more efficient system also at a population level if equity considerations continue to require a system of universal access to all the healthcare technology that will become available in the coming years. The other side of the coin of risk solidarity is the delimitation of the collective responsibility, thus of a basic benefit package. It is important to realize that equity has been a fundamental underlying value that has led to the creation of the healthcare systems as we know them but which may have become so accepted that it is no longer carefully considered when looking at issues of rationing or health reforms.

The impact of response bias on estimates of health care utilization in a metropolitan area: the use of administrative data.

BACKGROUND: Surveys among the general population are an important method for collecting epidemiological data on health and utilization of health care in that population. Selective non-response may affect the validity of these data. This study examines the impact of response bias on estimates of health care utilization and on risk estimates for utilization in relation to demographic and socioeconomic characteristics, using administrative data on use of health care. METHODS: Data on registered health care utilization were extracted from a health insurance register and linked to respondents (2,934; 62.7%) and non-respondents (1,744) in a personal health interview survey among adult residents from the lower two-thirds income bracket in Amsterdam, the Netherlands. RESULTS: Estimates of registered health care utilization are higher if based on respondents only, than if they are based on the entire target sample. This goes for prescription drugs, specialist medical care, paramedical care, dental care and medical aids, but not for hospital care. Most risk estimates of registered utilization for background characteristics (gender, family composition, marital status, year of settlement, affluence of neighbourhood and ethnicity) differ only slightly and without statistical significance. If different, most estimates based on respondents only are somewhat higher. The largest differences are found for age (average overestimation of risks for age groups 35-64 and 65+ years compared to that of 16-34 years: 16% and 17%, respectively). CONCLUSIONS: In this study, response bias affects estimates of registered health care utilization but hardly affects risk estimates of utilization by background characteristics.

Explaining educational differences in mortality: the role of behavioral and material factors.

OBJECTIVES: This study examined the role of behavioral and material factors in explaining educational differences in all-cause mortality, taking into account the overlap between both types of factors. METHODS: Prospective data were used on 15,451 participants in a Dutch longitudinal study. Relative hazards of all-cause mortality by educational level were calculated before and after adjustment for behavioral factors (alcohol intake, smoking, body mass index, physical activity, dietary habits) and material factors (financial problems, neighborhood conditions, housing conditions, crowding, employment status, a proxy of income). RESULTS: Mortality was higher in lower educational groups. Four behavioral factors (alcohol, smoking, body mass index, physical activity) and 3 material factors (financial problems, employment status, income proxy) explained part of the educational differences in mortality. With the overlap between both types of factors accounted for, material factors were more important than behavioral factors in explaining mortality differences by educational level. CONCLUSIONS: The association between educational level and mortality can be largely explained by material factors. Thus, improving the material situation of people might substantially reduce educational differences in mortality.

A longitudinal study of health selection in marital transitions.

We examined whether differences in health were associated with different probabilities of marital transitions in a longitudinal study, using Cox proportional hazard analysis. Data on approximately 10,000 Dutch persons of the GLOBE study, aged 15-74 years, were used for this purpose. The study started in 1991 and study subjects have been followed for 4.5 years. Of the four marital transitions studied (marriage among never married and divorced persons, and divorce and bereavement among married persons), only divorce among married persons was associated with health status: married persons who reported four or more subjective health complaints or two or more chronic conditions were, respectively, 1.5 and two times more likely to become divorced during follow-up than persons without these health problems. Since hardly any other studies have examined the role of health selection in marital transition with longitudinal data, more research is required before firm conclusions can be drawn. It can be concluded, however, that the frequently made assumption that health selection contributes only little to the explanation of health differences between marital status groups, seems, at least for the divorced, not justified.

Does childhood socioeconomic status influence adult health through behavioural factors?

BACKGROUND: The purpose of this study is to assess to what extent the effect of childhood socioeconomic status on adult health could be explained by a higher prevalence of unhealthy behaviour among those with lower childhood socioeconomic status. METHODS: Data were obtained from the baseline of a prospective cohort study in the Netherlands (13 854 respondents, aged between 25 and 74). Childhood socioeconomic group was indicated by occupation of the father, and adult health was indicated by perceived general health, health complaints and mortality. Adult socioeconomic status was measured by current occupation. Behavioural factors were smoking, alcohol consumption, Body Mass Index and physical activity. Relations were analysed using logistic regression models. RESULTS: A clear association between childhood socioeconomic circumstances and adult health was shown, as well as an association between childhood socioeconomic circumstances and health-related behaviour, even after adjustment for current socioeconomic status. Physical activity shows the strongest relation with childhood socioeconomic circumstances. Behavioural factors explain the relation between childhood socioeconomic status and adult health for approximately 10%. CONCLUSIONS: Childhood socioeconomic circumstances have an independent effect on adult health and health-related behaviour: the risk of health problems and health damaging behaviour is higher in lower childhood socioeconomic groups. The independent effect of childhood circumstances on adult health operates for a small part through unhealthy behaviour.

Socioeconomic inequalities in health in the working population: the contribution of working conditions.

BACKGROUND: The aim was to study the impact of different categories of working conditions on the association between occupational class and self-reported health in the working population. METHODS: Data were collected through a postal survey conducted in 1991 among inhabitants of 18 municipalities in the southeastern Netherlands. Data concerned 4521 working men and 2411 working women and included current occupational class (seven classes), working conditions (physical working conditions, job control, job demands, social support at work), perceived general health (very good or good versus less than good) and demographic confounders. Data were analysed with logistic regression techniques. RESULTS: For both men and women we observed a higher odds ratio for a less than good perceived general health in the lower occupational classes (adjusted for confounders). The odds of a less than good perceived general health was larger among people reporting more hazardous physical working conditions, lower job control, lower social support at work and among those in the highest category of job demands. Results were similar for men and women. Men and women in the lower occupational classes reported more hazardous physical working conditions and lower job control as compared to those in higher occupational classes. High job demands were more often reported in the higher occupational classes, while social support at work was not clearly related to occupational class. When physical working conditions and job control were added simultaneously to a model with occupational class and confounders, the odds ratios for occupational classes were reduced substantially. For men, the per cent change in the odds ratios for the occupational classes ranged between 35% and 83%, and for women between 35% and 46%. CONCLUSIONS: A substantial part of the association between occupational class and a less than good perceived general health in the working population could be attributed to a differential distribution of hazardous physical working conditions and a low job control across occupational classes. This suggests that interventions aimed at improving these working conditions might result in a reduction of socioeconomic inequalities in health in the working population.

Role of childhood health in the explanation of socioeconomic inequalities in early adult health.

STUDY OBJECTIVE: To examine the contribution of childhood health to the explanation of socioeconomic inequalities in health in early adult life. DESIGN: Retrospective data were used, which were obtained from a postal survey in the baseline of a prospective cohort study (the Longitudinal Study on Socio-Economic Health Differences in the Netherlands). Adult socioeconomic status was indicated by educational level, while health was indicated by perceived general health. Childhood health was measured by self reported periods of severe disease in childhood. Relations were analysed using logistic regression models. The reduction in odds ratios of "less than good" perceived general health for different educational groups after adjustment for childhood health was used to estimate the contribution of childhood health. SETTING: The population of the city of Eindhoven and surroundings in the south east of the Netherlands in 1991. PARTICIPANTS: 2511 respondents, aged 25-34 years, men and women, of Dutch nationality, were included in the analysis. MAIN RESULTS: There was a clear association between childhood health and adult health, as well as an association between childhood health and adult socioeconomic status. Approximately 5% to 10% of the increased risk of the lower socioeconomic groups of having a "less than good" perceived general health can be explained by childhood health. CONCLUSIONS: Childhood health contributes to the explanation of socioeconomic inequalities in early adult health. Although this contribution is not very large, it cannot be ignored and has to be interpreted largely in terms of selection on health.

A higher prevalence of health problems in low income groups: does it reflect relative deprivation?

STUDY OBJECTIVE: Although it has frequently been suggested that income affects health, there is hardly any research in which this issue has been explored directly. The aim of this study was, firstly, to examine whether income is independently associated with health, secondly, to assess the extent to which this association reflects high levels of deprivation in low income groups, and thirdly, to examine which specific components of deprivation contribute most to the link between income and health. Health indicators used were the prevalence of chronic conditions, health complaints and less than "good" perceived general health. SETTING: Region in the south east of the Netherlands. PARTICIPANTS: A population of 2567 men and women who participated in an oral interview, aged 15-74. DESIGN: Data were obtained from the baseline of a prospective cohort study aimed at the explanation of socioeconomic inequalities in health. RESULTS: Large inequalities in health by (equivalent) income after differences in other socioeconomic indicators had been controlled for were observed. For example, among those in the lowest income group the risk of bad perceived health was three times as high as among people in the highest income group. The prevalence of deprivation (basic, housing, social) increased with decreasing income to approximately 50-60% in the lowest income group. A substantial part of the increased health risks of the lowest income groups could statistically be accounted for by the higher prevalence of deprivation in these groups. The components that are likely to influence health indirectly, through a psychological or behavioural mechanism, accounted for most of the effect. CONCLUSIONS: These analyses provide evidence to suggest that a low income has detrimental health effects through relative deprivation. Moreover, the results indicate an indirect link between deprivation and health problems involving psychological or behavioural factors.
