Prospective epidemiological studies of beach water pollution were conducted in Hong Kong in the summers of 1986 and 1987. For the main study in 1987, a total of 18741 usable responses were obtained from beachgoers on nine beaches at weekends. The study indicated the overall perceived symptom rates for gastrointestinal, ear, eye, skin, respiratory, fever and total illness were significantly higher for swimmers than non-swimmers; and the swimming-associated symptom rates for gastrointestinal, skin, respiratory and total illness were higher at 'barely acceptable' beaches than at 'relatively unpolluted' ones. Escherichia coli was found to be the best indicator of the health effects associated with swimming in the beaches of Hong Kong. It showed the highest correlation with combined swimming-associated gastroenteritis and skin symptom rates when compared with other microbial indicators. A linear relationship between E. coli and the combined symptom rates was established. Staphylococci were correlated with ear, respiratory and total illness, but could not be used for predicting swimming-associated health risks. They should be used to complement E. coli. The setting of health-related bathing-water quality standards based on such a study is discussed.

Mental health and work stress among 653 office workers in Hong Kong were studied using Goldberg's 12-item general health questionnaire (GHQ), with slight modification, and McLean's self-assessment scheme in a self-administered questionnaire. It was found that more respondents reported symptoms in the six negative than in the six positive GHQ items. The proportions reporting problems in McLean's areas of coping, context, and stressors were 20.9%, 47.7%, and 14.8%, respectively. Females reported more problems in both context and coping than did males, but no difference was found between them for stressors. Multiple regression analysis revealed a strong association (r = .63) between mental ill health and McLean's three factors, with coping the most important factor for females, context the most important for males, and stressors the least important for both sexes in predicting mental ill health.

Mental health and work stress among 344 clerical (and secretarial) workers and 185 executives (96 managers and 89 executives) in Hong Kong was studied. No overall difference was found between clerical workers and executives in mental health and coping ability when sex was controlled for. Clerical workers, however, reported fewer interests, more problems in accepting others' values, and more dissatisfaction with work context. Female managers/executives were shown to be a high risk group, reporting more problems in mental health, coping, and work context than their male counterparts. Mental health was strongly associated with each of the work stress factors studied. A significant interaction between sex and nature of job was noted in predictors of mental health. The interaction of coping, context, and mental health is discussed.

In a case control study in Hong Kong, 445 cases of Chinese female lung cancer patients all confirmed pathologically were compared with 445 Chinese female healthy neighbourhood controls matched for age. The predominant histological type was adenocarcinoma (47.2%). The relative risk (RR) in ever-smokers was 3.81 (P less than 0.001, 95% CI = 2.86, 5.08). The RRs were statistically significantly raised for all major cell types with significant trends between RR and amount of tobacco smoked daily. Among never smoking women, RR for passive smoking due to a smoking husband was 1.65 (P less than 0.01, 95% CI = 1.16, 2.35) with a significant trend between RR and amount smoked daily by the husband. When broken down by cell types, the numbers were substantial only for adenocarcinoma (RR = 2.12, P less than 0.01, 95% CI = 1.32, 3.39) with a significant trend between RR and amount smoked daily by the husband. The results suggest that passive smoking is a risk factor for lung cancer, particularly adenocarcinoma in Hong Kong Chinese women who never smoked.
