[Smoking interventions in primary health care: smoking profile of women and beliefs and attitudes of local health care teams].

BACKGROUND: Chile has one of the highest prevalence rate of smoking in the world. Brief counseling interventions for smoking cessation at the primary health care level are effective. Compliance with counseling intervention is strongly associated with beliefs and attitudes of the primary health care team that deliver it. The effectiveness of these interventions improve if they are applied to smoking populations with higher motivation of change and high self-efficacy for quitting. AIM: To study the smoking profile of a group of smoking women in Santiago and to identify beliefs and attitudes of the primary health care team members to implement smoking cessation interventions. MATERIAL AND METHODS: A cross-sectional design that included 306 women smokers attending two primary health care clinics in Santiago. Perceptions, beliefs and attitudes of 34 primary care team members from three clinics in Santiago were explored using a qualitative methodology. RESULTS: The study identified a subgroup of 18% of women highly motivated to quit (decisional stage of change) and a 58% with a high self-efficacy. Beliefs and attitudes of staff at the clinics were characterized by invisibility, ambivalence and fatalism regarding the effectiveness of smoking cessation interventions. CONCLUSIONS: There is a subgroup of smoking women with a high probability of quitting if they receive an appropriate counseling. Developing a systematic approach for smoking cessation intervention at the primary care setting in Chile should consider the invisibility, ambivalence and fatalism of primary health care team members towards this topic.

Celebremos la salud! a community randomized trial of cancer prevention (United States).

BACKGROUND: Compared to non-Hispanic whites, Hispanics in the United States are at higher risk for certain types of cancer. METHODS: In a randomized controlled trial of 20 communities, we examined whether a comprehensive intervention influenced cancer screening behaviors and lifestyle practices in rural communities in Eastern Washington State. Cross-sectional surveys at baseline and post-intervention included interviews with a random sample of approximately 100 households per community. The interview included questions on ever use and recent use of Pap test, mammogram, and fecal occult blood test (FOBT) and sigmoidoscopy/colonoscopy, fruit and vegetable consumption and smoking practices. RESULTS: We found few significant changes in use of screening services for cervical (Pap test), breast (mammogram) or colorectal cancer (fecal occult blood test (FOBT) or sigmoidoscopy/colonoscopy) between intervention and control communities. We found no significant differences in fruit and vegetable consumption nor in smoking prevalence between the two groups. We found more awareness of and participation in intervention activities in the treatment communities than the control communities. CONCLUSIONS: Our null findings might be attributable to the low dose of the intervention, a cohort effect, or contamination of the effect in non-intervention communities. Further research to identify effective strategies to improve cancer prevention lifestyle behaviors and screening practices are needed.

Lay beliefs about hepatitis among North American Chinese: implications for hepatitis prevention.

The objective was to learn about the hepatitis prevention behavior of relatively unacculturated North American Chinese adults, along with their knowledge, beliefs, and perceptions with regard to hepatitis, screening, and vaccination. Forty Chinese men and women, aged 18-64, were recruited from immigrant communities in Seattle, Washington, and Vancouver, British Columbia. Semi-structured interviews (Cantonese or Mandarin) were audiotaped, translated, transcribed verbatim, and coded. Open coding, axial coding, constant comparison methods, and QSR NUD*IST 5 software was used for analysis. Findings were validated using eight focus groups. Findings indicated that many interviewees lack accurate knowledge with regard to hepatitis, often confusing the different types. Perceived causes of hepatitis included potentially harmful food (e.g., fried foods or potentially contaminated foods), alcohol, contact with infected individuals, stress, and inadequate rest. Preventive strategies associated with Chinese health beliefs included the use of Chinese herbal medicine, maintaining a stress-free mind, strengthening the body's natural defenses, and getting enough sleep. Other preventive strategies were the practice of good hygiene, vaccination, and the avoidance of contact with infected persons. Vaccination was not seen as primary, as 65% of those who had heard of hepatitis vaccination did not cite it as a means for hepatitis prevention until asked. Also, participants lacked information about the types and purposes of hepatitis vaccination and were worried about side effects. In conclusion, any attempt to promote hepatitis testing and vaccination among the North American Chinese should take traditional beliefs and practices into consideration.

Organophosphate pesticide exposure and work in pome fruit: evidence for the take-home pesticide pathway.

Organophosphate (OP) pesticides are commonly used in the United States, and farmworkers are at risk for chronic exposure. Using a sample of 218 farmworkers in 24 communities and labor camps in eastern Washington State, we examined the association between agricultural crop and OP pesticide metabolite concentrations in urine samples of adult farmworkers and their children and OP pesticide residues in house and vehicle dust samples. Commonly reported crops were apples (71.6%), cherries (59.6%), pears (37.2%), grapes (27.1%), hops (22.9%), and peaches (12.4%). Crops were grouped into two main categories: pome fruits (apples and pears) and non-pome fruits. Farmworkers who worked in the pome fruits had significantly higher concentrations of dimethyl pesticide metabolites in their urine and elevated azinphos-methyl concentrations in their homes and vehicles than workers who did not work in these crops. Among pome-fruit workers, those who worked in both apples and pears had higher urinary metabolites concentrations and pesticide residue concentrations in dust than did those who worked in a single pome fruit. Children living in households with pome-fruit workers were found to have higher concentrations of urinary dimethyl metabolites than did children of non-pome-fruit workers. Adult urinary concentrations showed significant correlations with both the vehicle and house-dust azinphos-methyl concentrations, and child urinary concentrations were correlated significantly with adult urinary concentrations and with the house-dust azinphos-methyl concentration. The results provide support for the take-home pathway of pesticide exposure and show an association between measures of pesticide exposure and the number of pome-fruit crops worked by farmworkers.

Child passenger safety behaviors in Latino communities.

Booster seats protect child occupants between 4 and 8 years of age. The objective of this study was to determine barriers and facilitators for booster seat use among Latino families. We conducted one-to-one elicitation interviews with 56 mothers and 35 fathers of booster-eligible Latino children in an urban county and a rural county in Washington State. Half of the parents did not consistently use booster seats. Interviews were recorded, transcribed, translated, and coded. Statements expressed by at least one-third of respondents were entered into explanatory models. Motivators for booster use were child safety and concern about getting a ticket. Facilitators for booster use included affordability, ease of use, and children liking the seat. Barriers were the belief that the child was too big/old, perceived child resistance, and cost. Rural parents preferred radio to television messages. Campaign messages highlighting the risks to child safety and the risk of a citation are likely to motivate booster seat use among Latino families.

Development of an English as a second language curriculum for hepatitis B virus testing in Chinese Americans.

Chinese Americans are at disproportionately high risk of liver cancer. A major risk factor for liver cancer in Asia is infection with hepatitis B virus (HBV): Approximately 80% of liver cancers are linked to HBV, and chronic carriers of HBV are > 100 times more likely to develop liver cancer compared with noncarriers. However, many adults, particularly those who have immigrated to the U.S., remain untested and therefore unvaccinated or unmonitored for the disease. Chinese Americans are mostly foreign born, and more recent arrivals face multiple social and health challenges. Many require special attention from public health professionals because of low levels of acculturation and difficulties learning English. It has long been established that an English as a Second Language (ESL) curriculum can teach immigrant adults and their family's important life skills, such as job training and citizenship. The authors report on their plans to develop and pilot test a culturally appropriate curriculum that will motivate Chinese ESL students to obtain a blood test for the detection of the HBV.

Colorectal carcinoma screening among Hispanics and non-Hispanic whites in a rural setting.

BACKGROUND: Colorectal carcinoma ranks as the second most common cancer and the second leading cause of cancer death in the United States. Hispanics are less likely than their non-Hispanic white counterparts to have ever received a fecal occult blood test (FOBT) or sigmoidoscopy/colonoscopy. Little is known about the barriers to screening in the Hispanic population. METHODS: The authors used baseline data from a community randomized trial of cancer prevention to compare screening prevalence and the associations between reported barriers and screening participation between Hispanics (n = 137) and non-Hispanic whites (n = 491) age > or = 50 years. RESULTS: Hispanics were less likely than non-Hispanic whites to have ever received an FOBT (P = 0.003) or sigmoidoscopy/colonoscopy (P = 0.001). No significant difference across ethnic groups was observed in the prevalence of recent screening using FOBT (29.8% for Hispanics vs. 34.5% for non-Hispanic whites; P = 0.41), but recent use of sigmoidoscopy/colonoscopy was lower for Hispanics (24.1% for Hispanics vs. 33.7% for non-Hispanic whites; P 0.06). Lacking health care coverage or having few years of education were directly associated with failure to ever receive an FOBT or sigmoidoscopy/colonoscopy. CONCLUSIONS: Interventions to improve adherence to colorectal carcinoma screening recommendations among Hispanics should target initial screening examinations, particularly among those lacking health care coverage or having low levels of education.

Improving physical fitness and emotional well-being in adolescents of low socioeconomic status in Chile: results of a school-based controlled trial.

Regular physical activity is associated with a reduced risk of all-cause mortality, and mortality due to cardiovascular disease and cancer. Among adolescents, physical activity is associated with benefits in the prevention and control of emotional distress, and improvement of self-esteem. Countries in transitional epidemiological scenarios, such as Chile, need to develop effective strategies to improve physical activity as a way to face the epidemic of chronic diseases. The objective of this study was to evaluate the effects of a school-based physical activity program on physical fitness and mental health status of adolescents living in a low socioeconomic status area in Santiago, Chile. A quasi-experimental design was used to evaluate the effects of the program over one academic year. The study included 198 students aged 15 years old. Two ninth grade classes were randomly selected as the intervention group, with two classes of the same grade as controls. A social planning approach was used to develop the intervention. The program was designed and implemented based on student preferences, teachers' expertise and local resources. Changes in physiological and mental health status were assessed. After the intervention, maximum oxygen capacity achieved a significant increase of 8.5% in the intervention versus 1.8% in the control group (p < 0.0001). Speed and jump performance scores improved significantly more in the intervention versus the control group (p > 0.01). Anxiety score decreased 13.7% in the intervention group versus 2.8% in the control group (p < 0.01), and self-esteem score increased 2.3% in the intervention group and decreased 0.1% in the control group after the end of the program (p < 0.0001). No significant change was observed in the depressive score. Student participation and compliance with the program was > 80%. To conclude, a school-based program to improve physical activity in adolescents of low socioeconomic status, obtained a high level of participation and achieved significant benefits in terms of physical fitness and mental health status.

Community-based participatory research: lessons learned from the Centers for Children's Environmental Health and Disease Prevention Research.

Over the past several decades there has been growing evidence of the increase in incidence rates, morbidity, and mortality for a number of health problems experienced by children. The causation and aggravation of these problems are complex and multifactorial. The burden of these health problems and environmental exposures is borne disproportionately by children from low-income communities and communities of color. Researchers and funding institutions have called for increased attention to the complex issues that affect the health of children living in marginalized communities--and communities more broadly--and have suggested greater community involvement in processes that shape research and intervention approaches, for example, through community-based participatory research (CBPR) partnerships among academic, health services, public health, and community-based organizations. Centers for Children's Environmental Health and Disease Prevention Research (Children's Centers) funded by the National Institute of Environmental Health Sciences and U.S. Environmental Protection Agency were required to include a CBPR project. The purpose of this article is to provide a definition and set of CBPR principles, to describe the rationale for and major benefits of using this approach, to draw on the experiences of six of the Children's Centers in using CBPR, and to provide lessons learned and recommendations for how to successfully establish and maintain CBPR partnerships aimed at enhancing our understanding and addressing the multiple determinants of children's health.

A short acculturation scale for Mexican-American populations.

Acculturation is important to examine variables that differentiate members of ethnic groups so that interventions can be appropriately targeted. By using a population-based sample of Mexican-origin adults, we sought to validate an acculturation scale for Mexican-American populations. The acculturation instrument included eight items adapted from the Acculturation Rating Scale for Mexican Americans (ARSMA). By using principal component analysis, we calculated eigenvalues for the eight items. The first principal component accounted for 66% of the variance. Language spoken most of the time, by itself, explained 62.4% of the variance of the full model, whereas birthplace, by itself, accounted for 74%. Slight increases in correlation values were observed beyond a four-item model that included language spoken most of the time, language thought, ethnic identity, and birthplace. Future studies should compare this scale with other multidimensional scales.

Health symptoms and exposure to organophosphate pesticides in farmworkers.

BACKGROUND: Few studies have examined the relationship between reported health symptoms and exposure to organophosphate (OP) pesticides. METHODS: Fisher's exact test was used to assess the relationship between self-reported health symptoms and indicators of exposure to OP pesticides in 211 farmworkers in Eastern Washington. RESULTS: The health symptoms most commonly reported included headaches (50%), burning eyes (39%), pain in muscles, joints, or bones (35%), a rash or itchy skin (25%), and blurred vision (23%). Exposure to pesticides was prevalent. The proportion of detectable samples of various pesticide residues in house and vehicle dust was weakly associated with reporting certain health symptoms, particularly burning eyes and shortness of breath. No significant associations were found between reporting health symptoms and the proportion of detectable urinary pesticide metabolites. CONCLUSIONS: Certain self-reported health symptoms in farmworkers may be associated with indicators of exposure to pesticides. Longitudinal studies with more precise health symptom data are needed to explore this relationship further.

Higher fat intake and lower fruit and vegetables intakes are associated with greater acculturation among Mexicans living in Washington State.

OBJECTIVE: To examine associations of diet with acculturation among Hispanic immigrants from Mexico to Washington state and to compare dietary patterns of Hispanic with non-Hispanic white residents. DESIGN: Data are part of the baseline assessment for a community-randomized cancer prevention trial. The Fat-Related Diet Habits questionnaire and the National 5-A-Day for Better Health program dietary assessment instruments were used to collect data on fat and fruit and vegetable intake, respectively. Data were also collected on demographic characteristics and acculturation status. SUBJECTS/SETTING: A total of 1,689 adult Hispanic and non-Hispanic white residents of 20 communities in the Yakima Valley, WA, completed in-person interviews. STATISTICAL ANALYSES PERFORMED: Mixed model regression analyses tested associations of acculturation with diet. These models compared the fat and the fruit and vegetable intake of Hispanics vs non-Hispanic white residents. Additional analyses compared the diets of highly acculturated Hispanics with low-acculturated Hispanics. All models included age, sex, income, and education and were also adjusted for the random effect of community. RESULTS: Dietary patterns varied by ethnicity and acculturation status. On average, compared with non-Hispanic white residents, Hispanics consumed one more serving of fruits and vegetables per day (P<.001). Dietary habits changed as Hispanics acculturated to the United States. Highly acculturated Hispanics ate fewer servings of fruits and vegetables per day compared with those not highly acculturated (P<.05). Highly acculturated Hispanics had slightly higher, but not statistically significant, scores on the Fat-Related Diet Habits questionnaire, which corresponds to a higher fat intake, compared with low-acculturated Hispanics. The early dietary changes made on acculturation included adding fat at the table to breads and potatoes. APPLICATIONS/CONCLUSIONS: Nutrition professionals should encourage their Hispanic clients to maintain their traditional dietary practices, such as a high intake of fruits and vegetables and eating bread and potatoes without added fat.

Use of Pap test among Hispanics and non-Hispanic whites in a rural setting.

BACKGROUND: Hispanic women in the United States have a higher incidence of invasive cervical cancer than non-Hispanic whites. A key factor related to the relatively high incidence is the underutilization of cancer-screening services. Several previous investigations have reported that Hispanic women are less likely to comply with screening recommendations for Pap testing; some have identified factors that are associated with non-compliance with screening recommendations. METHODS: Using baseline personal interview data from a randomized community trial on cancer prevention in a rural area, we assessed the association between health barriers and non-compliance with cervical screening recommendations. RESULTS: Among Hispanic women (n = 382), those with a lower level of acculturation were more likely than highly acculturated Hispanic and non-Hispanic white women (n = 385) to report personal barriers as reasons for not getting an initial or subsequent screening exam. Such barriers include fear of finding cancer, fear of finding diseases other than cancer, and embarrassment about receiving a physical exam. Certain structural barriers, such as cost of care, no time off work, and lack of transportation, were reported to be associated with non-compliance with routine cervical cancer screening, especially among non-Hispanic white women. CONCLUSIONS: Future research should examine barriers related to initial and subsequent screening among Hispanics with varying levels of acculturation.

Agricultural task and exposure to organophosphate pesticides among farmworkers.

Little is known about pesticide exposure among farmworkers, and even less is known about the exposure associated with performing specific farm tasks. Using a random sample of 213 farmworkers in 24 communities and labor camps in eastern Washington State, we examined the association between occupational task and organophosphate (OP) pesticide residues in dust and OP metabolite concentrations in urine samples of adult farmworkers and their children. The data are from a larger study that sought to test a culturally appropriate intervention to break the take-home pathway of pesticide exposure. Commonly reported farm tasks were harvesting or picking (79.2%), thinning (64.2%), loading plants or produce (42.2%), planting or transplanting (37.6%), and pruning (37.2%). Mixing, loading, or applying pesticide formulations was reported by 20% of our sample. Workers who thinned were more likely than those who did not to have detectable levels of azinphos-methyl in their house dust (92.1% vs. 72.7%; p = 0.001) and vehicle dust (92.6% vs. 76.5%; p = 0.002). Thinning was associated with higher urinary pesticide metabolite concentrations in children (91.9% detectable vs. 81.3%; p = 0.02) but not in adults. Contrary to expectation, workers who reported mixing, loading, or applying pesticide formulations had lower detectable levels of pesticide residues in their house or vehicle dust, compared with those who did not perform these job tasks, though the differences were not significant. Future research should evaluate workplace protective practices of fieldworkers and the adequacy of reentry intervals for pesticides used during thinning.

Attitudes and beliefs among Mexican Americans about type 2 diabetes.

Hispanics in the United States have a disproportionately high risk for non-insulin-dependent diabetes mellitus (type 2 diabetes) compared with non-Hispanic whites. Little is known of the attitudes and beliefs about diabetes in this group. Using data from six focus groups of 42 Mexican Americans (14 men and 28 women), we characterized perceptions about the causes of and treatments for type 2 diabetes. Many participants believed diabetes is caused by having a family history of the disease, eating a diet high in fat or sugar, and engaging in minimal exercise. Experiencing strong emotions such as fright (susto), intense anger (coraje), or sadness and depression (tristeza) was also thought to precipitate diabetes. Nearly all participants expressed the belief that it is important to follow doctors' recommendations for diet and exercise, oral medication or insulin; many also cited herbal therapies, such as prickly pear cactus (nopal) and aloe vera (savila) as effective treatments. These findings may be useful in designing interventions to reduce the burden of diabetes in Hispanic populations.

Household smoking bans: which households have them and do they work?

BACKGROUND: This study characterized Oregon households according to type and degree of restrictions on smoking and explored whether smoking restrictions are associated with decreased environmental tobacco smoke (ETS) exposure. METHODS: A population-based, random-digit-dialed cross-sectional telephone survey of 6,199 adult Oregonians was performed in 1997 to provide baseline data on tobacco use in Oregon. RESULTS: Seventy percent of Oregon households were composed of nonsmokers only, and 85% of those had a full ban on smoking inside the home. Of the households containing one or more smokers, 38% had a full household ban on smoking. Among respondents with a full ban in place, 99% of nonsmoker-only households reported that no one smoked in the home in the previous month, compared with 91% of households with at least one smoker. In both nonsmoker-only households and those with at least one smoker, full bans were strongly associated with awareness of the harm of ETS (OR = 12.8, 95% CI 7.3-22.3, and OR = 6.6, 95% CI 3.6-12.3, respectively). The presence of children in the household was also closely associated with full bans in the two types of households (OR = 4.6, 95% CI 2.8-7.6, and OR = 3.0, 95% CI 2.1-4.4, respectively). Nevertheless, 50% of households with children and a smoker present did not have a full ban in place. CONCLUSIONS: While the prevalence of household smoking restrictions is high in Oregon, there remains room for improvement, since 50% of households with a smoker and a child present do not have a full ban on indoor smoking. Public health messages that focus on household smoking restrictions may help protect nonsmokers from exposure to ETS.

Heavy smokers: a qualitative analysis of attitudes and beliefs concerning cessation and continued smoking.

In this qualitative analysis, we conducted intensive interviews of a group of heavy smokers to better understand psychosocial characteristics related to smoking and quitting. A total of 51 heavy smokers were recruited to participate in this study. In-depth interviews lasting 60-90 min explored factors related to smoking and attitudes toward cessation. N'Vivo was used to analyze the data. We modeled a number of factors related to heavy smoking in this population. A comprehensive model appeared to fit the data well. Key factors related to heavy smoking included those that promote smoking, those that influence quitting, perceptions of quitting, and explanations of failure. Along each of these dimensions, clusters of variables, such as the social environment, emotional identity, addiction, and physical health, emerged as being important in understanding the perceptions of heavy smokers when it comes to smoking and quitting. The models add important information to our understanding of heavy smokers. This work indicates that this sample of heavy smokers had many issues around smoking and quitting, including the perceived difficulty of quitting, physical and psychological addictions to smoke, reinforcement for smoking, and a tendency to procrastinate in quitting.
