Occupation and adult-onset asthma among Chinese women in a population-based cohort

BACKGROUND: Exposure to industrial irritants is believed to have contributed to the increasing prevalence of asthma worldwide. We examined the associations between occupation and asthma among women in a case-control study nested in the population-based Shanghai Women's Health Study cohort in China. METHODS: Cases were 1,050 women who reported a physician-diagnosed asthma as adults. Controls were 4,200 women matched to the cases by year of birth and age at diagnosis. Lifetime occupational histories were obtained. Logistic regression was applied to estimate odds ratios (ORs) adjusting for smoking, education, family income, and concurrent chronic bronchitis. RESULTS: Asthma is more prevalent in production industries for metal tools (OR = 2.4; 1.3-4.7), metal products for everyday use (OR = 1.6; 1.1-2.4), ships (OR = 2.6; 1.0-6.8), and clocks (OR = 1.9; 1.0-3.4), and in occupations as farm workers (OR = 4.0; 1.2-13.0), laboratory technicians and analyzers (OR = 2.2; 1.2-3.9), and installation and maintenance workers for weaving and knitting machineries (OR = 2.4; 1.1-5.4). Other associations less commonly reported were identified for electricians (OR = 2.1; 1.1-4.1), performers (OR = 3.2; 1.4-7.4), administrative workers in organizations and enterprises (OR = 1.8; 1.1-2.8), and postal and telecommunication workers (OR = 3.5; 1.6-7.6). CONCLUSIONS: Our findings suggest that occupational exposures contribute to the development of asthma in women.     

Occupation and oral cancer among women in the South

A case-control interview study among 232 North Carolina women with oral or pharyngeal cancer and 410 matched controls evaluated the contribution of occupation to the high risk of this cancer among females in the South. Review of detailed occupational histories found no overall elevated odds ratios for employment in the textile, apparel, or hosiery industry, the major employer of women in the area. Risks also did not increase with years worked in the industry. The findings thus fail to confirm an association reported in surveys in the United States and Great Britain. A new clue to occupational factors was suggested by the excess risk associated with the electronics industry in coastal North Carolina, independent of the participants' tobacco habits.     

Occupation and lung cancer risk among women in Northern China

Lifetime occupational histories were obtained in a case-control study of 965 female lung cancer patients and 959 controls selected from the general population in Shenyang and Harbin, People's Republic of China, where most women have worked outside the home. After adjusting for smoking, we found a significantly increased risk of lung cancer associated with employment involving the manufacture of transportation equipment (OR = 1.6, 95% CI = 1.0, 2.6), in particular the manufacturing of automobiles (OR = 3.0, 95% CI = 1.4, 6.4). Metal smelting and treatment workers were at an increased risk of lung cancer (OR = 1.5, 95% CI = 1.0, 2.1); the highest risks were observed among metal surfacers (OR = 3.1, 95% CI = 1.1, 9.0) and currently employed foundry workers (OR = 13.0, 95% CI = 1.7, 99.4). On the other hand, about a 50% decreased risk of lung cancer was observed among those employed in textile industries or as leaders of state and party organizations. Based on self-reports, exposures to coal dust and smoke from burning fuel at the workplace were also significant risk factors. The findings were similar when the analyses were confined to nonsmokers and were comparable across the major cell types of lung cancer. © 1993 Wiley-Liss, Inc.     

Occupation and meaning in the lives of women with chronic pain

The aim of this study was to examine how women experience occupations as they live with chronic pain and more specifically to gain detailed knowledge regarding the meaning of important occupations in their life. The article is based on an analysis of 17 narratives based on an Occupational Performance History Interview. Participants were interviewed as part of their occupational therapy assessment at Orton Rehabilitation. The narratives were analysed in order to identify the experiences of doing occupations in everyday life. When interpreting their problems in and solution for doing occupations women in this study used four basic metaphors: (1) moving forward, (2) slowing down, (3) fighting and (4) standing still. The tone of the narratives varied from hopeful to hopeless and from fearful to frustrated. Each of these four types of narratives differed in: (a) the tone of the narrative, (b) the meaning ascribed to occupation, (c) how others are viewed in relation to one's doing, and (d) how the future is envisioned. The experience of occupation in the lives of women with chronic pain is heterogeneous and depends on the underlying meaning of the narrative used to experience and interpret occupational life.

A survey of chronic bronchitis among brassware workers.

A stratified random sample of 580 workers aged between 18 and 50 years representing each sub-occupation in the brassware industry was studied for the prevalence of chronic bronchitis in relation to occupational and environmental factors. The findings were compared with those obtained in a reference group (N = 131) belonging to similar socio-economic status and unexposed to a dusty environment. Although the exposed group showed higher prevalence of chronic bronchitis in comparison to that observed in the controls (10.5 vs 5.3%), the difference was not significant at the 5% level. It was observed that the workers engaged in non-dusty occupations such as brass sheet cutting and engraving showed the lowest prevalence of the disease (5.0%) while those engaged in the dusty occupations viz., casting, soldering, electroplating and polishing showed the highest prevalence (12.0%). The smoking adjusted odds ratios calculated in various sub-occupations showed the highest risk of developing chronic bronchitis among the polishers (2.74). Though the risk in other occupational sub-groups was double, it did not attain a level of significance. The smoking adjusted odds ratios in relation to length of exposure showed that the risk was significantly higher among the workers exposed for over 10 years compared to those who worked for less than 10 years in the grinding, soldering and brass ingot making operations. The study thus showed a dose-response relationship between length of exposure and chronic bronchitis while effect of age on the disease was not discernible probably due to the small number of cases and the young age of the study group. The concentration of various metals in the air samples drawn from the work environment where main processes were in operation, was low compared to the prescribed level by ACGIH.     

Occupation and breast cancer risk among Shanghai women in a population-based cohort study

INTRODUCTION: A total of 74,942 female subjects were recruited in a population-based cohort study in Shanghai, China between 1997 and 2000. We examined the relationship between occupation and breast cancer risk. METHODS: Cases were 586 women previously diagnosed with breast cancer at baseline and 438 women newly diagnosed with breast cancer during follow-up through December 2004. Eight controls were randomly selected for each case from cancer-free cohort members and frequency-matched to the cases by year of birth and age at diagnosis. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) of breast cancer risk associated with occupations, adjusting for established breast cancer risk factors. RESULTS: In the prevalent breast cancer data analysis, increased risks of breast cancer were associated with technicians in engineering/agriculture/forestry (OR = 1.6, CI: 1.0-2.4), teaching personnel (OR = 1.5, CI:1.1-2.0), tailoring/sewing workers (OR = 1.6, CI:1.0-2.7), and examiners/measurers/testers (OR = 1.5, CI:1.1-2.1) among those who started the jobs at least 20 years ago. Among incident breast cancer cases, significantly increased risks were associated with medical/health care workers (OR = 1.4, CI:1.0-2.0), administrative clerical workers (OR = 1.5, CI:1.0-2.4), postal/telecommunication workers (OR = 2.2, CI:1.0-5.5), and odd-job workers (OR = 1.7, CI:1.1-2.8) among those who started the jobs at least 20 years ago. The excess risks were found in both prevalent and incident cases for postal/telecommunication workers and purchasing/marketing personnel, although ORs reached only marginal significance. CONCLUSIONS: This study suggests that white-collar professionals and several production occupations may be associated with an increased risk of breast cancer.     

Chronic bronchitis among nonsmoking farm women in the agricultural health study

OBJECTIVE: The purpose of this study was to examine agricultural risk factors for chronic bronchitis among nonsmoking farm women. METHODS: We used self-reported enrollment data from the 21,541 nonsmoking women in the Agricultural Health Study to evaluate occupational risk factors for prevalent chronic bronchitis among farm women. Odds ratios (ORs) for chronic bronchitis for occupational exposures were adjusted for age, state, and related agricultural exposures. RESULTS: Applying manure and driving combines were independently associated with chronic bronchitis. Off-farm job exposures associated with chronic bronchitis were organic dusts, asbestos, gasoline, and solvents. Five pesticides were associated with chronic bronchitis after multivariate adjustment and sensitivity analyses: dichlorvos (OR=1.63, 95% CI=1.01, 2.61), DDT (OR=1.67, 95% CI=1.13, 2.47), cyanazine (OR=1.88, 95% CI=1.00, 3.54), paraquat (OR=1.91, 95% CI=1.02, 3.55), and methyl bromide (OR=1.82, 95% CI=1.02, 3.24). CONCLUSION: Pesticides as well as grain and dust exposures were associated with chronic bronchitis among nonsmoking farm women.     

Pesticide use and chronic bronchitis among farmers in the Agricultural Health Study

BACKGROUND: Farmers have increased risk for chronic bronchitis. Few investigators have considered pesticides. METHODS: We evaluated pesticides as risk factors for chronic bronchitis using the Agricultural Health Study enrollment data on lifetime pesticide use and history of doctor-diagnosed chronic bronchitis from 20,908 private pesticide applicators, primarily farmers. RESULTS: A total of 654 farmers (3%) reported chronic bronchitis diagnosed after age 19. After adjustment for correlated pesticides as well as confounders, 11 pesticides were significantly associated with chronic bronchitis. Heptachlor use had the highest odds ratio (OR=1.50, 95% Confidence Interval (CI)=1.19, 1.89). Increased prevalence for chronic bronchitis was also seen for individuals who had a history of a high pesticide exposure event (OR=1.85, 95% CI=1.51, 2.25) and for those who also applied pesticides in off-farm jobs (OR=1.40, 95% CI=1.04, 1.88). Co-morbid asthma and current farm activities did not explain these results. CONCLUSIONS: These results provide preliminary evidence that pesticide use may increase chronic bronchitis prevalence.     

Screening mammography among Chinese Canadian women

BACKGROUND: Though breast cancer is the most common malignancy among Chinese women, screening mammography is underutilized. This study examined barriers and facilitators of screening mammography among Chinese Canadian women. METHODS: Using community-based sampling, Chinese women in British Columbia were interviewed in 1999 about multiple preventive health behaviours. We included 213 women in the mammography analysis; main outcome measures were ever having a mammogram and routine mammography. RESULTS: Seventy-five percent of women 50 to 79 years old reported ever having had a mammogram, and 53% had two or more mammograms within the last five years. Receiving a recommendation for a mammogram from medical personnel or from a family member, and believing that cancer cannot be prevented by faith were independently associated with both screening outcomes. CONCLUSIONS: A multifaceted approach to screening mammography promotion in Chinese Canadian women is suggested. Interventions that include education of and by medical providers and family members should be considered.     

Occupation of women and maternal and child health

This study was carried out in Dahanu taluka of Thane district in the state of Maharashtra, India, in October 1987 using cluster sampling. 10 clusters from 9 primary health centers were selected, which yielded 1954 families and a representative population of 7800. The distribution of various occupations among the women indicated that 1127 were housewives, 594 were agricultural laborers, 19 were skilled workers, 118 were unskilled workers, and 96 were engaged in other work. Regarding family income, 304 housewives earned 1000 rupees or more vs. 63 working mothers; 423 housewives earned 500-999 rupees vs. 451 working mothers; and 393 housewives earned 250-4999 rupees vs. 214 working mothers. As far as prenatal care was concerned, among housewives, 861 did not get any care, 190 had fewer than 3 visits, and 14 had over 3 visits. Among agricultural laborers, 533 did not get any care, 14 had fewer than 3 visits, and 2 had 3 or more visits. Among skilled workers, the respective figures were 10, 7, and 0. Among housewives, prenatal problems consisted of edema (18), anemia (7), and bleeding (36). The respective figures for agricultural laborers were 8, 21, and 26. Among housewives, 270 were attended by trained health workers at birth and 794 were attended by untrained health workers. The respective figures for agricultural laborers were 251 and 298; for unskilled workers, 20 and 94; and for skilled workers, 10 and 7. Among housewives, prolonged labor and malposition occurred in 4 cases, but these were absent in 1062 cases. The respective figures for working mothers were 9 and 673. Similarly, excessive bleeding or fever occurred in 9 housewives but were absent in 1059. The respective figures for working women were 2 and 679. Pregnancy outcome among housewives included 867 FTND, 2 very low birth weight, 3 safe birth?, 3 abortions, and 8 neonatal deaths. Among working women, the respective figures were 548, 3, 2, 1, and 6. Socioeconomic factors are linked to the level of health, and hard physical labor can adversely affect it.

Breast self-examination among Chinese immigrant women.

The incidence of breast cancer is rising rapidly among the fast-growing demographic group of Asian American and Pacific Islanders (AAPIs). In this study, the authors assessed the awareness of breast self-exam (BSE) and factors predicting practice of BSE among Chinese immigrant women living in San Francisco. Three hundred and ninety-seven women participated in a telephone survey; 80.9% reported having heard of BSE but only 53.9% reported practice of BSE during the past year. Logistic regression modeling found that increased length of stay in the United States, higher income, socializing with more Chinese than non-Chinese, and a birthplace other than U.S. and Chinese communities predicted BSE practice. The findings indicate that although familiarity with BSE is high among this group of Chinese immigrant women, self-reported actual practice is far from optimal. This study points to the need for culturally appropriate interventions that will encourage and motivate immigrant Chinese women to practice BSE on a monthly basis.
