The efficacy of personalized audiovisual patient-education materials.

Patient education is considered an important component of primary care medicine. The traditional methods of patient education have been physician-patient dialogue and printed handouts. This study compares the relative efficacy of pamphlets, one-to-one dialogue, and audiovisual presentations. The results indicate that the slide and sound presentation was most effective in conveying patient information.

Quality of life at the end of life: trends in patients with metastatic prostate cancer.

OBJECTIVES: To identify the rates of decline in health-related quality of life during the year before death in men with prostate cancer. METHODS: We studied men in a subset analysis within a longitudinal, observational cohort of patients with metastatic prostate cancer at the University of California, Los Angeles, Center for Health Sciences. The analysis included 23 patients who died and had submitted at least two health-related quality-of-life surveys in the final months before death. The outcomes were measured with the RAND 36-Item Health Survey, an established, validated instrument that includes physical and emotional domains. To gauge the effect of marital status, education, and income, we dichotomized these demographic variables. RESULTS: Most domains showed declines, many of them substantial. Patients who had a slower rate of decline in the physical domains tended to be married, better educated, and more affluent. We noted a trend toward a slower deterioration in the mental composite scores among patients who had less than a college degree and an annual household income of $30,000 or less. CONCLUSIONS: Patients dying of metastatic prostate cancer appear to experience declines in health-related quality of life during their final year of life. Further investigation may help identify specific patient characteristics associated with more rapid declines; this will help focus attention on enhancing patients' quality of life as death approaches.

Bipolar disorder: similarities and differences between patients with illness onset before and after 65 years of age.

BACKGROUND: Recent reports have suggested that bipolar disorder beginning in late life is strongly associated with organic brain disease whereas early-onset cases are more likely to be associated with a family history of mood disorder. It is not yet clear whether late-onset bipolar disorder is therefore a "phenocopy" of the classic early-onset disorder, sharing symptoms but having a different etiology, or whether people with early- and late-onset bipolar disorder have a common underlying vulnerability that interacts with age-specific triggering factors. AIM: The present study examines the administrative records of patients treated for bipolar disorder, to establish whether differences between early- and late-onset cases might be consistent with their having distinct etiological processes. METHODS: We used a file containing administrative data for all patients with a diagnosis of bipolar disorder who were in contact with the health services of Western Australia between 1980 and 1998. For each contact with psychiatric services, the file provided the patient's age, gender, marital status, educational achievement, employment, ethnic origin, postcode of residence, primary and secondary diagnoses, and the duration of the (administrative) episode. Subjects were designated "late-onset" when their first contact with psychiatric services occurred at or after 65 years of age. RESULTS: Between 1980 and 1998 there were 33,004 service contacts involving 6,182 individuals whose primary or secondary clinical diagnosis was bipolar disorder. This indicates that the prevalence of bipolar disorder in Western Australia is approximately 0.4%. Most patients had an onset of illness between 15 and 45 years of age, but 492 patients (8%) were aged 65 years or over at the time of first contact with mental health services. We observed that the relative frequency of late-onset bipolar disorder increased between 1980 and 1998 (1% to 11%). There was an excess of women in our cohort (3:2), but no difference in the age of onset between males and females. Early onset was associated with a subsequently lower socioeconomic status, aboriginal ethnicity, and a higher frequency of mixed affective episodes, other mood disorders, schizophrenia, and schizoaffective disorder. Patients with late-onset bipolar disorder were more likely to have a diagnosis of organic mental disorder recorded (2.8% vs. 1.2%). There was no evidence of a bimodal pattern of age-specific incidence. CONCLUSION: The observed differences between early- and late-onset bipolar disorders are small and most likely attributable to differences in the duration of illness. Only a small proportion of patients with bipolar disorder were ever diagnosed with an organic mental disorder, which suggests that the reported association between late onset of illness and organic factors may be of limited clinical relevance.

Quality of life in Korean patients with inflammatory bowel diseases: ulcerative colitis, Crohn's disease and intestinal Behçet's disease.

Health-related quality of life (HRQOL) is an important outcome factor in chronic diseases such as inflammatory bowel disease (IBD). This study used the Korean translation of the disease-specific, self-administered Inflammatory Bowel Disease Questionnaire (IBDQ) to compare HRQOL in ulcerative colitis (UC; n = 98), Crohn's disease (CD; n = 49), and intestinal Behçet's disease (BD; n = 34). In addition to the current status, patients were asked retrospectively to recall their symptoms at the beginning and during the worst period of their disease. Disease activity was measured by St. Mark's Activity Index, Crohn's disease Activity Index (CDAI), and the Harvey-Bradshaw Index (HBI). In all IBD patients, including those with BD, the IBDQ total score during the worst period was significantly lower than that at present and that at the beginning of the disease. However, there were no significant differences between groups regarding the total IBDQ score or its various dimensions. In UC a strong correlation between IBDQ scores and St. Mark's Activity Index was observed (r = -0.708, P < 0.001). IBDQ scores were also highly correlated with CDAI and HBI in both CD (r = -0.506, P < 0.001 for CDAI; r = -0.600, P < 0.001 for HBI) and BD (r = -0.687, P < 0.001 for CDAI; r = -0.531, P < 0.001 for HBI). However, the current IBDQ score was not related to demographic parameters such as gender, age, educational status, economic status, and marital status as well as disease factors such as duration of disease, history of operation or hospital admission, extent of disease in UC, involved region in CD, and clinical type in BD. We conclude that the Korean IBDQ is a responsive and promising instrument for measuring HRQOL of IBD patients in clinical trials. In addition, the IBDQ can be helpful in developing a disease-specific activity index in BD.

Association of hypertensive status and its drug treatment with lipid and haemostatic factors in middle-aged men: the PRIME study.

AIMS: To assess the association of hypertensive status and antihypertensive drug treatment with lipid and haemostatic levels in middle-aged men. METHODS AND RESULTS: Hypertensive status, antihypertensive drug treatment, total and high-density lipoprotein (HDL) cholesterol, triglyceride, apoproteins A-I and B, lipoparticles LpA-I, LpE:B and Lp(a), fibrinogen, plasminogen activator inhibitor-1 (PAI-1) activity and factor VII were assessed in a sample of men 50-59 years living in France (n = 7050) and Northern Ireland (n = 2374). After adjustment for age, body mass index, smoking status, educational level, country, alcohol drinking and hypolipidaemic drug treatment, untreated hypertensive subjects had higher levels of total cholesterol, triglyceride, apoproteins A-I and B and PAI-I activity than normotensive subjects. On univariate analysis, diuretics decreased total and HDL-cholesterol and apoproteins A-I and B; those differences remained after multivariate adjustment. Treatment with beta-blockers decreased total and HDL-cholesterol, apoprotein A-I and LpA-I, and this effect remained after multivariate adjustment. Calcium channel blockers decreased total cholesterol and apoproteins A-I and B; those differences remained significant after multivariate adjustment. ACE inhibitors decreased total cholesterol, triglycerides, apoprotein B and LpE:B; and this effect remained after multivariate adjustment. Analysis of the subjects on monotherapy showed beta-blockers to decrease total cholesterol and HDL parameters and angiotensin-converting enzyme (ACE) inhibitors to decrease low-density lipoprotein (LDL)-related parameters, while no effect was found for the other antihypertensive drugs. CONCLUSIONS: Hypertensive status is associated with an unfavourable lipid and haemostatic profile in middle-aged men. Antihypertensive treatment with beta-blockers decreases HDL parameters, whereas treatment with ACE inhibitors appears to decrease total cholesterol and LDL-related parameters.

Fatigue in pregnancy: a comparative study.

The objective of this study was to use validated scales to determine if fatigue is increased during the first trimester of pregnancy compared to nonpregnant women with similar demographic characteristics. Women between 6 and 12 weeks' gestation were invited to complete a demographics questionnaire and the Numerical Rating Scale for Fatigue (NRS-F), State Trait Anxiety Inventory (STAI), and Beck Depression Index (BDI-II). Nonpregnant women were also invited to participate. Statistical analysis was performed using Mann-Whitney U, Fisher's exact, Spearman correlation, and Monte Carlo tests where appropriate; significance was assumed at p <0.05. Twenty pregnant and 15 nonpregnant patients were enrolled. There was no difference in age, parity, BMI, race, marital status, education, income or hours worked outside the home between pregnant and nonpregnant subjects. Pregnant women reported greater number of hours spent sleeping each day (8 [7-10] vs. 7 [6-9], p = 0.03). There was no significant difference in BDI-II, STAI-S, or STAI-T scores, but pregnant women had significantly higher scores on the NRS-F test (72.5 [20-88] vs. 36 [18-94], p <0.05). Women in the first trimester of pregnancy experience significantly greater fatigue compared to a similar group of nonpregnant women.

Physiological parameters associated with psychogenic sexual arousal in women with complete spinal cord injuries.

OBJECTIVE: To compare the physiological sexual responses of women with complete spinal cord injuries (SCIs) with those of able-bodies women. DESIGN: Controlled laboratory-based analysis of responses to audiovisual erotic and audiovisual erotic combined with manual stimulation. SETTING: The sexual physiology laboratory at our free-standing rehabilitation hospital. PARTICIPANTS: A volunteer sample of 13 women with complete SCIs above T6 along with eight able-bodies women, matched for age and educational status. INTERVENTIONS: A 78-minute protocol using 6-minute baseline alternating with 12-minute testing conditions was conducted. DEPENDENT VARIABLES: Included vaginal pulse amplitude, subjective arousal, heart rate, blood pressure, and respiratory rate. RESULTS: Showed comparable increases in subjective arousal in both groups with audiovisual but not audiovisual combined with manual stimulation. Vaginal pulse amplitude increased in able-bodied subjects but no SCI subjects with isolated audiovisual stimulation; however, with the addition of manual stimulation all subjects responded similarly. Other nongenital correlates of sexual arousal were similar between SCI and able-bodies subjects. CONCLUSION: These results provide physiological validation of the hypothesis that women with complete SCI can respond with audiovisual stimulation similarly to able-bodies women in those functions that are controlled neurologically above the level of their injuries, whereas, genital vasocongestion will not occur because the neurological pathway is interrupted. In contrast, reflex genital vasocongestion can occur in women with complete SCI despite a lack of subjective arousal. These findings can be used to educate women with complete SCIs about their sexual responses.

Socio-demographic risk factors for perinatal mortality. A study of perinatal mortality in the French district of Seine-Saint-Denis.

OBJECTIVES: To investigate the impact of a set of socio-demographic risk factors commonly associated with perinatal mortality -- age, parity, marital status, educational attainment, occupation, and ethnic origin in the French district of Seine-Saint-Denis. METHODS: The study has a case-control design with prospective identification of cases. It includes all singleton non-malformed perinatal deaths which occurred between October 1, 1989 and September 30, 1992. Logistic regression is used to estimate odds ratios. Base incidence rates are generated by incorporating sampling information for the controls. RESULTS: All socio-demographic variables are significantly related to the risk of perinatal mortality in univariate analyses. Some of the increased risk due to social factors is explained by differential age and parity distributions. In multivariate models, however, only parity and country of origin are significant. Women born in the French overseas departments and territories and Sub-Saharan Africa have the highest odds ratios. CONCLUSIONS: Women born outside of continental France face an elevated risk of experiencing a perinatal death even after controlling for age, parity and socioeconomic factors. Although, this excess risk may reflect residual variation in socioeconomic status, alternative explanations such as standards of prenatal care, medical problems during pregnancy and delivery, and cultural practices should be explored.

Prevalence of obsessive-compulsive disorder in Iran.

BACKGROUND: Estimates of the annual prevalence for Obsessive Compulsive Disorder (OCD) were consistent across the international sites range, 1.9%-2.5%. The nine population surveys, which used Diagnostic Interview Schedule, estimated a six-month prevalence of OCD ranging from 0.7% to 2.1%. This study performed in order to determine the prevalence of OCD in a population-based study among Iranian adults aged 18 and older and to study the association of them with factors such as sex, marital status, education, type of occupation and residential area. METHODS: A cross-sectional nationwide epidemiological study of the Iranian population aged 18 and older was designed to estimate the prevalence of psychiatric disorders and their association with the above mentioned factors. 25180 individuals were selected and interviewed through a randomized systematic and cluster sampling method from all Iranian households. Schedule for Affective Disorders and Schizophrenia (SADS) and Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) criteria were used in diagnosis of OCD. 250 clinical psychologists interviewed the selected subjects face to face at their homes. RESULTS: The prevalence of OCD in Iran is 1.8% (0.7% and 2.8% in males and females; respectively). 50.3% of the survey sample were men, 49.9% women, 29.1% single, 67.45% married, 0.4% separated or divorced, 2.5% widow/widower and 4% undetermined. All of the above-mentioned factors were examined in the univariate and multivariate logistic regression models. Although the data did not fit the models well, but in univariate models, sex, the category "single" of marital status, age, the categories "business" and "housewife" and residential areas showed significant effect adjusting for the factors, but the models didn't fit the data properly. CONCLUSION: The study suggests that the prevalence of OCD is not rare in the community of Iran and is within the range of other countries. Similar to prior studies in other communities, OCD is more common in females than males.

Do geographic and educational factors influence the quality of life in rectal cancer patients with a permanent colostomy?

PURPOSE: This study was designed to evaluate possible social and geographic factors that could have an impact on quality of life in patients after abdominoperineal excision of the rectum. Although the number of patients with rectal cancer who need to be treated with abdominoperineal excision of the rectum and construction of permanent colostomy has greatly decreased in the past, there is still controversy about the influence on quality of life caused by this procedure. METHODS: In a prospective trial, patients operated on for low rectal cancer by abdominoperineal excision of the rectum were evaluated by a quality of life questionnaire, modified from The American Society of Colon and Rectal Surgeons questionnaire, to assess fecal incontinence. The results for the four domains of quality of life (lifestyle, coping behavior, embarrassment, depression), as well as for subjective general health, were evaluated with regard to age, gender, education, and geographic origin in univariate and multivariate analyses. RESULTS: Thirteen institutions in 11 countries included data from 257 patients. Although the analysis of general health did not reveal any significant differences, the analysis of the four quality of life domains showed the significant influence of geographic origin. The presence of a permanent colostomy showed a consistently negative impact on patients in southern Europe as well as for patients of Arabic (Islamic) origin. On the other hand, age, gender, and educational status did not reveal a statistically significant influence. CONCLUSIONS: This is the first study to show the influence of geographic origin on quality of life of patients with a permanent colostomy. Possible factors that may influence the outcome of patients after surgical treatment of rectal cancer, such as weather, religion, or culture, should be taken into account when quality of life evaluations are considered.

Who consults and where? Sociocultural differentiation in access to health care in urban Africa.

Sociocultural differentiation in health behaviour was studied among 500 mothers randomly chosen in the suburban area of Dakar, Senegal. Variables were age, marital status, educational level, socioeconomic conditions, urban experience, town integration, village attachment, social insurance, ethnic group and disease categories. Access to health care was considered for the last illness of the mother and her youngest child under five. Town integration and disease category (and social insurance for children) were the only variables correlated with the number of consultations. Socioeconomic level and social insurance (and educational level for mothers) were associated with preference for private rather than public health systems.

Need for recovery after work predicts sickness absence: a 2-year prospective cohort study in truck drivers.

BACKGROUND: Incomplete recovery from work-related fatigue after work (i.e., sustained activation) is assumed to mediate the relation between the exposure to stressful working conditions and the development of health problems. The need for recovery after work scale reflects the extent to which workers have difficulties to recover adequately from work-related fatigue after a working day. OBJECTIVES: The aim of this study was to establish if need for recovery after work in truck drivers (1). predicts future sickness absence (>14 working days) and (2). mediates the prospective relation between stressful working conditions (low control, high job demands) and sickness absence. METHODS: Self-administered questionnaires, providing information about need for recovery after work, sickness absence, job control, and job demands (psychological, physical, and supervisor job demands), were sent to a random sample of 2000 drivers in 1998. Of the 1123 responders, 820 returned a completed questionnaire 2 years later (response 72%). This study was restricted to the 526 participants who still worked at follow-up as a truck driver at the same company. RESULTS: High baseline need for recovery after work was associated with an increased risk for subsequent sickness absence (odds ratio [OR] 2.19, 95% confidence interval [CI] 1.13-4.24) after adjustment for age, previous sickness absence, marital status, educational level, and company size. Additional adjustment for baseline stressful working conditions led to a marginally reduction of the excess risk for sickness absence. CONCLUSIONS: High need for recovery after work increases the risk of subsequent sickness absence that is not explained by relevant (non-) work-related factors. However, the results did not testify that need for recovery after work mediates between the exposure to stressful working conditions, and the subsequent occurrence of sickness absence. Practically, the results indicate that monitoring recovery complaints in truck drivers may assist practitioners to take efficient preventive measures at the appropriate time.

Knowledge that upper respiratory tract infection resolves on its own is associated with more appropriate health-seeking behaviour and antibiotic cognition.

INTRODUCTION: This study aims to study whether knowledge that upper respiratory tract infection (URTI) resolves on its own is associated with more appropriate antibiotic cognition and treatment-seeking behaviour in adult patients seeking consultation for upper respiratory tract symptoms in all nine polyclinics of the National Healthcare Group in Singapore. METHODS: A prospective study of 595 adult patients who attended for URTI symptoms of less than seven days duration was performed. We collected data using an interviewer-administered structured questionnaire eliciting the participant's personal and demographical data, his knowledge about URTI, past experience with URTI and treatment-seeking behaviour for this current episode of URTI. These variables were then regressed against the variable "URTI resolves on its own", adjusting for "antibiotics relieve URTI faster", "antibiotic used unnecessarily for URTI", "recovery faster with antibiotics" for antibiotic cognition; and "number of days with URTI", "first line of action: self-medicate", "reason for attendance: felt unwell", "reason for attendance: get well faster" and "used prescribed medication before current visit" for health-seeking behaviour. RESULTS: More than one-third of patients believed that URTI resolved on its own. Subjects who believed that URTI resolved on its own were not significantly different in terms of gender, ethnic group, educational status, age, knowledge of germs as causal, and number of days sick before attendance. However, such patients were 1.68 times (confidence interval [CI] 1.17, 2.41) more likely to agree that, nowadays, antibiotics are used unnecessarily for "flu", and 2.07 times (CI 1.32, 3.24) more likely to self-medicate. They were 0.51 (CI 0.35, 0.76) times more likely to be dependant on prescribed medication. CONCLUSION: Knowledge that URTI resolves on its own is associated with more appropriate antibiotic cognition and health-seeking behaviour.

Lack of association between Alzheimer's disease and education, occupation, marital status, or living arrangement.

Using the resources of the Rochester Epidemiology Project, we conducted a case-control study of sociodemographic characteristics using the incidence cohort of patients with Alzheimer's disease (AD). During the conduct of ongoing studies of AD in Rochester, we identified new cases of AD as they occurred during 1975-1979 (N = 241). We selected one age- and sex-matched control from among all registrations for care in this community during the year of onset for each case. There was little difference between cases and controls for educational attainment, marital status, type of dwelling, living arrangement, or occupation. We were unable to confirm low educational level as a risk factor for AD in this population. Future attempts to identify etiologic risk factors for dementing illness should probably move toward other areas of research.

Growth of breast-fed and formula-fed infants from 0 to 18 months: the DARLING Study.

Anthropometric data were collected monthly from birth to 18 months as part of the Davis Area Research on Lactation, Infant Nutrition and Growth study, which followed infants who were either breast-fed or formula-fed during the first 12 months. The two cohorts were matched for parental socioeconomic status, education, ethnic group, and anthropometric characteristics and for infant sex and birth weight, and neither group was given solid foods before 4 months. While mean weight of formula-fed infants remained at or above the National Center for Health Statistics median throughout the first 18 months, mean weight of breast-fed infants dropped below the median beginning at 6 to 8 months and was significantly lower than that of the formula-fed group between 6 and 18 months. In contrast, length and head circumference values were similar between groups. Weight-for-length z scores were significantly different between 4 and 18 months, suggesting that breast-fed infants were leaner. The groups had similar weight gain during the first 3 months, but breast-fed infants gained less rapidly during the remainder of the first year: cumulative weight gain in the first 12 months was 0.65 kg less in the breast-fed group. Length gain was similar between groups. These results indicate that weight patterns of breast-fed infants, even in a population of high socioeconomic status, differ from current reference data and from those of formula-fed infants. Thus, new growth charts based on breast-fed infants are needed.

Effects of health insurance and race on early detection of cancer.

BACKGROUND: The presence and type of health insurance may be an important determinant of cancer stage at diagnosis. To determine whether previously observed racial differences in stage of cancer at diagnosis may be explained partly by differences in insurance coverage, we studied all patients with incident cases of melanoma or colorectal, breast, or prostate cancer in Florida in 1994 for whom the stage at diagnosis and insurance status were known. METHODS: The effects of insurance and race on the odds of a late stage (regional or distant) diagnosis were examined by adjusting for an individual's age, sex, marital status, education, income, and comorbidity. All P values are two-sided. RESULTS: Data from 28 237 patients were analyzed. Persons who were uninsured were more likely diagnosed at a late stage (colorectal cancer odds ratio [OR] = 1.67, P =.004; melanoma OR = 2.59, P =.004; breast cancer OR = 1.43, P =.001; prostate cancer OR = 1.47, P =.02) than were persons with commercial indemnity insurance. Patients insured by Medicaid were more likely diagnosed at a late stage of breast cancer (OR = 1.87, P<.001) and melanoma (OR = 4.69, P<.001). Non-Hispanic African-American patients were more likely diagnosed with late stage breast and prostate cancers than were non-Hispanic whites. Hispanic patients were more likely to be diagnosed with late stage breast cancer but less likely to be diagnosed with late stage prostate cancer. CONCLUSIONS: Persons lacking health insurance and persons insured by Medicaid are more likely diagnosed with late stage cancer at diverse sites, and efforts to improve access to cancer-screening services are warranted for these groups. Racial differences in stage at diagnosis are not explained by insurance coverage or socioeconomic status.

Reference limits for routine haematological measurements in 7-14-year-old children living at an intermediate altitude (1869 m, Erzurum, Turkey).

In order to obtain reference limits, complete blood counts were performed using an automated haematology analyser (Cell-Dyn 1500) on venous blood samples from 718 healthy children living at 1869 m altitude. At first, to obtain appropriate populations for obtaining reference values, the factors of per capita income, parental educational status and antecedent infection(s) were assessed with respect to their effects on each parameter. Of the subgroups classified according to these factors, those which were affected in terms of haematological values were excluded. The effects of age and sex on the parameters were evaluated, and reference values were arranged according to age groups to facilitate clinical use. Among the reference values which we suggest for children living at about 2000 m altitude, those of haemoglobin, haematocrit, red blood cell count and mean cell volume are significantly higher than sea-level values. In addition, our results indicate that intermediate altitude has no effect on other routine haematological values.

Total serum homocysteine, folate and vitamin B12 in a Greek school age population.

BACKGROUND & AIMS: Moderate hyperhomocysteinemia is an independent risk factor for cardiovascular disease (CVD) even among children. The purpose of this study is to investigate for the first time the distribution and determinants of total serum homocysteine (tHcy) levels in healthy Greek children. METHODS: tHcy, folate, B12 were measured in 524 children (275 boys and 249 girls) aged 6-15 years old from different socioeconomic status in Northern Greece. RESULTS: The geometric mean tHcy level for boys and girls was 7.8 (3.4-24.2) and 7.5 (3.9-29.0) micromol/L, respectively. Eighty one (15.4%) children had homocysteine levels above the upper reference limits (>10 micromol/L). The geometric mean serum tHcy level was significantly (P<0.001) increasing with age; 6.4 (3.4-11.2) micromol/L was found in the age group of 6-9 yr (group1), 7.2(4.1-22.1) micromol/L in the one of 10-12 yr (group 2) and 8.5 (3.9-29.0) micromol/L in the one of 13-15 yr (group 3). Serum folate levels were found to be statistically significant (P<0.001) between age group 1 and age group 3 [11.8 (4.66-20.00) vs. 7.5 (0.99-20.00)ng/mL) and between age group 2 and 3 [10.0 (1.82-20.0) vs. 7.5 (0.99-20.00)ng/mL]. Vitamin B12 levels were significantly (P<0.001) different in the three age groups [1048 (117-2000), 805 (296-2000), 700 (214-2000)pg/mL] respectively. Age, BMI, waist circumference (WC), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were positively correlated with tHcy, whereas serum folate and vitamin B12 were negatively correlated. No association was found between tHcy levels and parental education status. In multiple linear regression analysis only age (Beta: 0.248, 95%, CI: (0.159-0.361), P<0.05) and folate (Beta: 0.347, 95%, CI: [(-0.206)-(-0.118)], P<0.05) were found significantly and independently associated with tHcy. CONCLUSIONS: tHcy levels were increasing with age and boys were found to have slightly higher levels than girls. Age and folate levels were the most significantly and independently determinants associated with tHcy. Children with tHcy levels above the upper reference limits (>10 micromol/L) were found to be correlated with BMI, WC, SBP, serum folate and vitamin B12 levels. These children should be encouraged to include high folate food items in their diet and where necessary folate supplements should be recommended. In addition, more prospective studies are necessary in order to evaluate the relationship of tHcy and CVD risk factors in children of our region.
