BACKGROUND: Childhood caloric restriction may lead to permanent changes in the hypothalamopituitarygonadal axis, which could lead to impaired female reproductive ability. We assessed the effect of childhood exposure to the 19441945 Dutch famine on subsequent female reproductive function. METHODS: This was a population-based cohort study in Utrecht, The Netherlands. Between 1983 and 1985, 6030 women born between 19321941 were classified by questionnaire according to their famine exposure experiences. Dates of marriage, first and second childbirth, and information on a medical reason for having no children or fewer children than wanted were available from questionnaires, as well as ages and type of menopause. RESULTS: Severe famine exposure during childhood significantly decreased chances of first and second childbirth at any given time after marriage or first childbirth [adjusted hazard ratios (HR) 0.86, 95% confidence interval (CI) 0.760.96; and HR 0.87, 95% CI 0.780.97, respectively). Risk of a medical reason for having no or fewer children than wanted was increased in the severely exposed (odds ratio 1.88; 95% CI 1.292.74), as was the risk of a surgical menopause (HR 1.53; 95% CI 1.271.84). CONCLUSIONS: Our findings support the presence of longstanding modest effects of childhood famine exposure on reproductive function in women.
