Abstract
Objectives: Based on a life-course approach, the purpose of this study is to analyze how the age at the birth of a first child moderates the relationship between childhood socioeconomic position (SEP) and cardiovascular diseases (CVD) incidence in old age, separately for women and men. Methods: We used a rich and representative life history survey of people aged from 65 to 75 living in Santiago, Chile (n = 802), and weighted multivariate statistical models. Data collection process involved the use of face-to-face life history calendars, administered by well-trained interviewers. Results: Early motherhood increases the risk of suffering CVD among older women with a disadvantaged childhood SEP, while late motherhood decreases it. By contrast, early fatherhood decreases CVD risk among older men with an adverse childhood SEP, while late fatherhood increases it. Conclusion: Our findings about the moderating role of parenthood onset on CVD risk among older women and men with a disadvantaged childhood SEP contributes to public health reflections on unexplored cardiovascular risk factors, which lead to substantial changes in women’s and men’s life courses, and might optimize cardiovascular prevention strategies.
