Sex differences in minor psychiatric morbidity.
This monograph is concerned with some epidemiological observations of minor psychiatric morbidity. Differences in rates of specific disorders have historically formed a crucial part of epidemiological enquiry. Sex differences in the prevalence of minor affective disorders have been demonstrated in studies of populations in treatment and in community populations, and have been variously ascribed to constitutional or environmental factors. A review of the literature exposes the methodological problems of measurement and study design, and the conflicting nature of the findings. Efforts have recently concentrated on establishing the social factors important in the aetiology of minor affective disorder without adequate exclusion of constitutional factors. The importance of life events, chronic social stress and inadequate social supports in the aetiology of minor affective disorder has been demonstrated, but the variance explained by such factors is small, reinforcing the view that constitutional factors of some kind are likely to be of importance. The evidence for a genetic contribution to minor affective disorder is tenuous, but there is circumstantial evidence that changes in gonadal hormones are linked to mood changes in women. Until further evidence is available this must remain a powerful possibility in the genesis of sex differences in minor affective disorder. This investigation used epidemiological methods to assess whether there is a sex difference in the constitutional vulnerability of the male and female phenotype to minor psychiatric morbidity. In order to minimize the effects of environment and of sex roles and stereotypes as far as possible, a sample of relatively homogeneous employed men and women (drawn from a population of executive officers in the Home Office) was studied. The data obtained from this population of men and women of similar age, education, occupation and social environment were compatible with the null hypothesis that there is no sex difference in the prevalence of minor psychiatric morbidity, or its outcome in such a homogeneous group. However, women did report significantly more somatic symptoms than men. The second hypothesis, that there is a substantial sex difference in the self-perception of illness, illness behaviour and sickness absence in individuals with minor psychiatric morbidity among a homogeneous group of men and women of similar age, education and occupation, and subject to similar levels of social stress and support, received only partial support from the findings of the study.(ABSTRACT TRUNCATED AT 400 WORDS)
