The effect of moderate son preference on family size is analysed using data from the 1982 Sri Lanka Contraceptive Prevalence Survey whose respondents were followed-up in the 1985 Sri Lanka Contraceptive Survey. Reported reproductive intentions on desire for additional children were not always reflected in overall contraceptive use. Complicating factors were the use of modern and traditional methods and the role of induced abortion. Longitudinal observations of the 1982-85 period relating women's individual reproductive behaviour to their intentions show no consistent behavioural difference between those with and without sons. However, at any given parity, the proportion reporting at least one additional child born during the intersurvey period was higher among those women who intended to have at least one additional child than among those who wanted to stop childbearing. This analysis suggests that son preference finds expression more through reproductive intentions than through actual fertility behaviour in the follow-up period.
利用1982年斯里兰卡避孕普及率调查的数据，分析了适度的男孩偏好对家庭规模的影响，该调查的受访者在1985年斯里兰卡避孕调查中接受了随访。报告的关于想要更多孩子的生育意愿并不总是反映在总体避孕措施的使用上。复杂因素包括现代和传统方法的使用以及人工流产的作用。对1982 - 1985年期间将女性个体生育行为与其意愿相关联的纵向观察表明，有儿子和没有儿子的女性在行为上没有一致的差异。然而，在任何给定的胎次中，打算至少再要一个孩子的女性中，报告在两次调查期间至少又生育了一个孩子的比例高于那些想要停止生育的女性。该分析表明，在后续阶段，男孩偏好更多地通过生育意愿而非实际生育行为表现出来。
