Pesticide take-home pathway among children of agricultural workers: study design, methods, and baseline findings.

Farmworkers are exposed to pesticides and may take home pesticide residues to their families. In this paper, self-reported pesticide exposure and home practices to reduce the amount of pesticide residues taken home were examined among 571 farmworkers. Urine samples from a subsample of farmworkers and children and dust samples from households and vehicles also assessed pesticide exposure. Overall, 96% of respondents reported exposure to pesticides at work. Many employers did not provide resources for hand washing. Farmworkers' protective practices to keep pesticide residues out of the home were at a low level. In a subset of respondents, pesticide levels above the limit of quantitation were seen in the urine of children and adults and in house and vehicle dust. The results support the take-home pathway of pesticide exposure. Ways must be found to reduce this pesticide exposure among children of farmworkers.

Colorectal cancer screening among African Americans: the importance of physician recommendation.

INTRODUCTION: African Americans have higher colorectal cancer incidence and mortality rates than whites. They are also more likely to be diagnosed with late-stage disease and less likely to survive for at least five years after diagnosis. Lack of adherence to colorectal cancer screening recommendations has previously been found to be associated with lower income, lower educational level, and racial/ethnic minority status. METHODS: One hundred-fifty African-American patients (aged 50-79 years) of an inner city hospital, were surveyed by mail and telephone in early 2002. Seventy-six patients completed the survey, and data from 74 surveys were analyzed. RESULTS: Approximately one-half (55%) of the respondents reported having received a fecal occult blood test (FOBT) in the last 12 months, sigmoidoscopy in the last five years, or colonoscopy in the last 10 years. Thirty-nine percent of the survey participants reported never having received a physician recommendation for FOBT, 60% reported never having received a recommendation for sigmoidoscopy, and 57% reported never having received a recommendation for colonoscopy. Previous physician recommendation was strongly associated (p < 0.001) with levels of FOBT, sigmoidoscopy, and colonoscopy use. DISCUSSION: Future studies should examine factors that influence primary care physicians' decision-making about ordering colorectal cancer screening tests, as well as patients' decision-making regarding adherence to physician recommendations.

A randomized controlled trial of interventions to promote cervical cancer screening among Chinese women in North America.

BACKGROUND: North American Chinese women have lower levels of Papanicolaou (Pap) testing than other population subgroups. We conducted a randomized controlled trial to evaluate the effectiveness of two alternative cervical cancer screening interventions for Chinese women living in North America. METHODS: Four hundred and eighty-two Pap testing underutilizers were identified from community-based surveys of Chinese women conducted in Seattle, Washington, and Vancouver, British Columbia. These women were randomly assigned to one of two experimental arms or control status. Several Chinese-language materials were used in both experimental arms: an education-entertainment video, a motivational pamphlet, an educational brochure, and a fact sheet. Women in the first experimental group (outreach worker intervention) received the materials, as well as tailored counseling and logistic assistance, during home visits by trilingual, bicultural outreach workers. Those in the second experimental group (direct mail intervention) received the materials by mail. The control group received usual care. Follow-up surveys were completed 6 months after randomization to ascertain participants' Pap testing behavior. All statistical tests were two-sided. RESULTS: A total of 402 women responded to the follow-up survey (83% response rate). Of these women, 50 (39%) of the 129 women in the outreach group, 35 (25%) of the 139 women in the direct mail group, and 20 (15%) of the 134 women in the control group reported Pap testing in the interval between randomization and follow-up data collection (P<.001 for outreach worker versus control, P =.03 for direct mail versus control, and P =.02 for outreach worker versus direct mail). Intervention effects were greater in Vancouver than in Seattle. CONCLUSION: Culturally and linguistically appropriate interventions may improve Pap testing levels among Chinese women in North America.

Costs and cost-effectiveness of a clinical intervention to increase mammography utilization in an inner city public health hospital.

BACKGROUND: Studies have demonstrated the cost-effectiveness of screening women for breast cancer; however, the cost-effectiveness of strategies to motivate women to receive breast cancer screening has been less well studied. METHODS: A total of 196 women, aged 50 to 74, who were enrolled in a public health hospital clinic, were noncompliant with mammography screening, and had at least one routine clinic appointment during the study period (15 months) were entered into a randomized, controlled trial of a motivational intervention to increase mammography rates. Costs were captured via a modified Delphi technique, accounting records, sampling of staff time logs, and an estimation of miscellaneous and overhead costs. Summary costs were calculated using Excel spread sheets. RESULTS: Overall, 49% of women who received the intervention had a mammogram within 8 weeks of an index visit compared with 22% of control women. Calculation of the cost-effectiveness of the project showed an additional cost of $151 (1996 U.S.$) for each woman receiving the intervention and $559 for each additional woman motivated to receive a mammogram. CONCLUSIONS: Cost tracking and cost-effectiveness analysis can be done when intervening in a clinical setting, thereby allowing clinics to make informed decisions about implementing programs to increase motivation of their patients to receive screening.

Some design issues in a community intervention trial.

We present statistical considerations for the design of a 20-community randomized trial. The community intervention aims at multiple cancer prevention health behaviors including reducing dietary fat, increasing fruit and vegetable intake, smoking cessation, and increasing colorectal cancer screening. To better measure the overall impact of the intervention, individual endpoints as well as a global test of multiple endpoints are used. The statistical power analysis takes into account the heterogeneity between communities, the correlation between health behaviors over time, and the correlation between multiple endpoints. The study is being conducted in a relatively confined geographic area. Several measures have been taken to account for potential contamination. These include collecting information in baseline and follow-up surveys on intervention dose and conducting surveys in three similar communities in another part of the state.

Evaluation of an outreach intervention to promote cervical cancer screening among Cambodian American women.

INTRODUCTION: Southeast Asian women have low levels of Papanicolaou (Pap) testing participation. We conducted a group-randomized controlled trial to evaluate a cervical cancer screening intervention program targeting Seattle's Cambodian refugee community. METHODS: Women who completed a baseline, community-based survey were eligible for the trial. Neighborhoods were the unit of randomization. Three hundred and seventy survey participants living in 17 neighborhoods were randomized to intervention or control status. Intervention group women received home visits by outreach workers and were invited to group meetings in neighborhood settings. The primary outcome measure was self-reported Pap testing in the year prior to completing a follow-up survey. RESULTS: The proportion of women in the intervention group reporting recent cervical cancer screening increased from 44% at baseline to 61% at follow-up (+17%). The corresponding proportions among the control group were 51 and 62% (+11%). These temporal increases were statistically significant in both the intervention (P < 0.001) and control (P = 0.027) groups. DISCUSSION: This study was unable to document an increase in Pap testing use specifically in the neighborhood-based outreach intervention group; rather, we found an increase in both intervention and control groups. A general awareness of the project among women and their health care providers as well as other ongoing cervical cancer screening promotional efforts may all have contributed to increases in Pap testing rates.

Cancer prevention behaviors and socioeconomic status among Hispanics and non-Hispanic whites in a rural population in the United States.

OBJECTIVES: Socioeconomic status is explored as a predictor of differences between Hispanics and non-Hispanic Whites in cancer prevention behavior. METHODS: In a cross-sectional study, in-person interviews (n = 1795) were conducted in a population-based random sample of adults in 20 communities with a high proportion of Hispanics. RESULTS: Hispanics were significantly less likely than non-Hispanic Whites to ever have had cervical (p < 0.001), breast (p = 0.007), or colorectal cancer (FOBT p = 0.008; sigmoidoscopy/colonoscopy p < 0.002) screening. After adjusting for socioeconomic status (education and having health insurance), only differences in cervical cancer remained significant (p = 0.024). After adjusting for socioeconomic status, Hispanics had a significantly higher intake of fruits and vegetables per day (4.84 servings) than non-Hispanic Whites (3.84 servings) (p < 0.001); and fat behavior score was marginally significant after adjustment for socioeconomic status (p = 0.053). Significantly fewer Hispanics were current smokers than non-Hispanic Whites (p < 0.001). CONCLUSIONS: There is only limited support for the hypothesis that socioeconomic status is a major determinant of some cancer-related behaviors; specifically, socioeconomic status is related to mammography and colorectal screening, but not cervical cancer, dietary behavior, or smoking.

Evaluation of take-home organophosphorus pesticide exposure among agricultural workers and their children.

We analyzed organophosphorus pesticide exposure in 218 farm worker households in agricultural communities in Washington State to investigate the take-home pathway of pesticide exposure and to establish baseline exposure levels for a community intervention project. House dust samples (n = 156) were collected from within the homes, and vehicle dust samples (n = 190) were collected from the vehicles used by the farm workers to commute to and from work. Urine samples were obtained from a farm worker (n = 213) and a young child (n = 211) in each household. Dust samples were analyzed for six pesticides, and urine samples were analyzed for five dialkylphosphate (DAP) metabolites. Azinphosmethyl was detected in higher concentrations (p < 0.0001) than the other pesticides: geometric mean concentrations of azinphosmethyl were 0.53 micro g/g in house dust and 0.75 micro g/g in vehicle dust. Dimethyl DAP metabolite concentrations were higher than diethyl DAP metabolite concentrations in both child and adult urine (p < 0.0001). Geometric mean dimethyl DAP concentrations were 0.13 micro mol/L in adult urine and 0.09 micro mol/L in child urine. Creatinine-adjusted geometric mean dimethyl DAP concentrations were 0.09 micro mol/g in adult urine and 0.14 micro mol/g in child urine. Azinphosmethyl concentrations in house dust and vehicle dust from the same household were significantly associated (r2 = 0.41, p < 0.0001). Dimethyl DAP levels in child and adult urine from the same household were also significantly associated (r2 = 0.18, p < 0.0001), and this association remained when the values were creatinine adjusted. The results of this work support the hypothesis that the take-home exposure pathway contributes to residential pesticide contamination in agricultural homes where young children are present.

[Cost-effectiveness analysis of a preventive program for gallbladder disease in Chile].

BACKGROUND: Chilean women have one of the highest mortality rates from gallstone disease in the world. There is no primary prevention for the disease and the benefits of prophylactic cholecystectomy in high risk groups have not been studied. AIM: To analyze the cost and effectiveness of a screening program for gallbladder disease in the Chilean women population. METHODS: A decision analytic model is used to compare lifetime cost and effectiveness of standard care with three screening strategies. The first two strategies consider "universal ultrasound screening" for all women 40 years old and laparoscopic cholecystectomy for those with gallstones ("elective intervention") or with calculous > or = 3 cm ("high risk intervention"). The third strategy is based on "selective screening" for obese women. RESULTS: The lifetime probability of a 40 years old Chilean woman of dying from gallbladder disease is reduced by 70% in the universal screening/elective intervention, by 63% in the high risk intervention and by 18% in the selective screening strategy. Her lifetime expectancy increases by 5.25, 4.64 and 1.24 months respectively. The incremental cost-effectiveness ratio of each screening strategy is US$ 180, US$ 147 and US$ 481 respectively. CONCLUSION: A screening program for gallbladder disease in a high risk population achieves significant benefits at a low incremental cost and acceptable cost-effectiveness.

Assessing cervical cancer risk in Hispanics.

Population-based cancer registries rely on various methods to assign Hispanic ethnic identifiers to patients in the registry. The methods may result in misclassification of patient ethnic identities. Such misclassification may obscure the real incidence of cervical cancer among Hispanic women. This review summarizes previous literature on the accuracy of methods used to ascertain Hispanic ethnicity in numerator and denominator data for the calculation of cancer incidence. In addition, cancer registry ethnicity ascertainment methods were examined for six United States states (California, Florida, Illinois, New Mexico, New York, and Texas) that have a high proportion of Hispanics. The percentage of persons classified as Hispanic who self-identified as Hispanic (predictive value positive) in various reported studies ranged from 54 to 76% for women. The accuracy of ethnicity assignments based on either the United States census list or the Generally Useful Ethnic Search System (GUESS) program show slight differences in percentages of self-identified Hispanics who were classified as Hispanic (sensitivity among women: 62-80% for 1980 United States census list, 63-82% for GUESS program). Higher sensitivity and lower predictive value positive is achieved with a greater number of sources used. In conclusion, decisions about collecting racial and ethnicity information are influenced by demographic changes, immigration trends, changes in ethnic and racial identity, legislative needs, and public policies. The rapidly growing Hispanic population and the excess incidence of cervical cancer in this population requires improving the accuracy of ethnicity information.

Methodologic advances and ongoing challenges in designing community-based health promotion programs.

Community intervention trials continue to attract researchers as potential ways to achieve widespread, long-term change in health behaviors. The first generations of community studies were somewhat unsophisticated in design and analysis, and their promise may have been overstated. As design and analysis issues were better defined, as secular trends caught up with the behaviors that researchers were trying to change, or as other unknown variables affected community studies, small effects of interventions were observed in community trials. Discussions were held in professional meetings and reported in the literature: Should community trials be discontinued? In general, the answer was a qualified no. In this paper, we briefly review some of the many advances made in community intervention trials, and address in more detail the challenges ahead.

Tobacco Use by Chinese American Men: An Exploratory Study of the Factors Associated with Cigarette Use and Smoking Cessation.

PURPOSE: There is little information on cigarette use and smoking cessation in Asian Pacific Islanders. This study explored factors associated with tobacco use in the largest Asian American ethnic group - Chinese American men. METHODS: Chinese American men age 17 or older, recruited by convenience sampling, were interviewed by a male trilingual and bicultural interviewer. Open&shy;ended, semi&shy;structured interviews were coded using PRECEDE framework under two categories&colon; cigarette use and smoking cessation. FINDINGS: Smoking, favorably perceived and valued, plays an important role in Chinese society. Lack of appropriate information and some beliefs pose challenges to effective tobacco control. Participants expressed willingness to adhere to no smoking rules and regulation. Attitudes and perceptions in the U.S. towards cigarette smoking, which differ from those in China, reinforce attitudes more favorable to smoking cessation. CONCLUSIONS: Themes elicited challenge mainstream smoking cessation approaches for Chinese American men. Further exploration of these results are needed to develop effective tobacco control in this and possibly other Asian American populations.

Cervical Cancer among Asian American Women: A Neglected Publica Health Problem?

PURPOSE OF THE PAPER: Relatively little attention has been paid to cervical cancer control in Asian American populations. We summarize available cervical cancer incidence and mortality dat, present information on levels of Pap testing use, and review factors that may be associated with cervical cancer screening participation. METHODS: We reviewed the literature pertaining to cervical cancer and Pap testing among Asian populations in North America. PRINCIPAL FINDINGS: Cancer registry data suggest that women from Southease Asia have a nearly five&shy;fold increased risk of invasive cervical cancer &lpar;when compared to non&shyHispanic White women&rpar;. Filipino and Korean populations also have elevated risks. The excess invasive cervical cancer burden appears to be concentrated among women aged 40 and older. Pap testing use by Asians is less than for all toher racial/ethnic groups in the U.S., and recent studies suggest that over one&shy;third of Vietnamese immigrants have never been screened. Barriers to Pap testing participation by less acculturated Asian women include a lack of familiarity with Western preventive concepts, a lack of knowledge concerning cervical cancer, embarrassment in association with gynecologic exams, the role of women in some Asian cultures, the cost of health care, and language difficulties. CONCLUSIONS: There is a considerable need for ethnoculturally appropriate cervical cancer control programs targeting Asian American populations. RELEVANCE TO ASIAN PACIFIC ISLANDER AMERICAN POPULATIONS: This paper is relevant to Asian American women from East, South, Southeast, and Island Asia.

A case-based clinician training program for treating tobacco use in college students.

Tobacco use rates are high among college students, and while many of them try to quit every year, only a small percentage are successful at maintaining abstinence. Most colleges have campus health centers that offer treatment for tobacco cessation, but few students access these resources. Little is known about how to motivate young adult college students to seek treatment or assist them in their attempts to quit smoking. In the context of a comprehensive, group-randomized intervention study to decrease smoking among college students, a case-based tobacco cessation training program for campus health center providers and staff was developed and conducted at 14 intervention colleges during the 2003-2004 academic year. Six case studies were created for this training, using responses from 39 student elicitation interviews conducted at 12 colleges in Spring 2002. Common themes relating to smoking, quitting, and relapse experiences reported by students in the elicitation interviews were woven into the cases and integrated into the training program.

Preferred smoking policies at 30 Pacific Northwest colleges.

OBJECTIVE: Research shows that restrictive smoking policies on college campuses could discourage smoking onset or help facilitate cessation efforts among students. However, many colleges and universities are reluctant to establish restrictive smoking policies for fear of student objections. Our study examined preferred smoking policies among college students in the Pacific Northwest. METHODS: We conducted a baseline cross-sectional descriptive study of a grouped randomized controlled trial at 30 four-year colleges and universities in Idaho, Oregon, and Washington. RESULTS: Of the 14,237 students who responded to the survey, 17.3% were smokers. All respondents were knowledgeable about indoor smoking policies; however, there was incongruence regarding outside policies. Some 88% of never smokers wanted a completely smoke-free indoor policy, while a substantial percentage (58%) of smokers concurred (odds ratio [OR]=0.19, p<0.001). Fewer respondents were supportive of outdoor policies (43.3% for never smokers and 6.9% for smokers). Respondents agreed that the desire to breathe clean air should have priority over the desire to smoke; however, smokers agreed to a lesser extent (97.5% for never smokers and 81.5% for smokers [OR=0.012, p<0.001]). CONCLUSION: Both non-smokers and smokers have high approval rates for restrictive smoking policies on campus. Administrators can use this information to help enact restrictive campus smoking policies.

Factors related to participatory employee advisory boards in small, blue-collar worksites.

PURPOSE: To identify factors related to formation, participation, and characteristics of employee advisory boards (EABs) in blue-collar worksites. DESIGN: This study used a nonexperimental qualitative design to assess EAB formation, activity, and enthusiasm levels and examined those factors relative to employee participation in worksite-wide health promotion activities. SETTING: Twenty-two blue-collar worksites with a total of 113 EAB members in the greater Seattle area. SUBJECTS: Individuals who agreed to serve on EABs in the intervention worksites. INTERVENTION: Participants received training in involving employees in the 5-A-Day project intervention activities. MEASURES: Measures include type of worksite, number of EAB members, method of EAB recruitment, and variables describing EAB functioning, including attendance at meetings, assistance at project activities, and level of enthusiasm. RESULTS: All worksites formed EABs. There was no association between the way the EAB was formed and subsequent EAB attendance at meetings, participation in project activities, representativeness of the EAB, or level of EAB enthusiasm. Enthusiasm of the EAB was associated with employee participation, and EABs with a higher level of enthusiasm showed more participation by employees than worksites with less enthusiastic EABs. CONCLUSIONS: It is possible to develop participatory structures in small, blue-collar worksites. More information is needed about factors related to levels of enthusiasm of EABs.

Adolescents' smoking behaviors, beliefs on the risks of smoking, and exposure to ETS in Juárez, Mexico.

OBJECTIVE: To assess the smoking behaviors, beliefs about the risks of smoking, and exposure to ETS among adolescents in Juárez, Mexico. METHODS: A cross-sectional study was conducted with sixth-grade students (N=506), aged 11-13 years old, attending 6 randomly selected schools. Schools were classified by school setting and SES. RESULTS: Students attending a low SES school setting were more likely to have smoked (P < 0.01), be current smokers (P < 0.01), be exposed to ETS at home and in public (P < 0.01) than were students attending a middle or high SES school. CONCLUSION: Smoking interventions should target students attending school in low SES settings.
