Stressful Life Events, the Incidence of Infertility, and the Moderating Effect of Maternal Responsiveness: A Longitudinal Study Journal of Developmental Origins of Health and Disease 12,3 (June 2021): 465-473.

Although the association between stress and poor reproductive health is well established, this association has not been examined from a life course perspective. Using data from the National Longitudinal Survey of Youth 1997 cohort (N = 1652), we fit logistic regression models to test the association between stressful life events (SLEs) (e.g., death of a close relative, victim of a violent crime) during childhood, adolescence, and early adulthood and later experiences of infertility (inability to achieve pregnancy after 12 months of intercourse without contraception) reported by female respondents. Because reactions to SLEs may be moderated by different family life experiences, we stratified responses by maternal responsiveness (based on the Conger and Elder Parent-Youth Relationship scale) in adolescence. After adjusting for demographic and environmental factors, in comparison to respondents with one or zero SLEs, those with 3 SLEs and ≥ 4 SLEs had 1.68 (1.16, 2.42) and 1.88 (1.38, 2.57) times higher odds of infertility, respectively. Respondents with low maternal responsiveness had higher odds of infertility that increased in a dose–response manner. Among respondents with high maternal responsiveness, only those experiencing four or more SLEs had an elevated risk of infertility (aOR = 1.53; 1.05, 2.25). In this novel investigation, we demonstrate a temporal association between the experience of SLEs and self-reported infertility. This association varies by maternal responsiveness in adolescence, highlighting the importance of maternal behavior toward children in mitigating harms associated with stress over the life course.

2.	Differential Secular Trends in BMI in Relation to Region of Childhood Residence: A 25 Year Follow-up of a Nationally Representative Sample Presented: Boston MA, American Public Health Association Annual Meeting and Expo, November 2013 Cohort(s): NLSY79 Publisher: American Public Health Association Keyword(s): Body Mass Index (BMI); Childhood Residence; Modeling, Random Effects; Obesity; Regions; Weight Permission to reprint the abstract has not been received from the publisher. Although regional variations in prevalence of overweight and average BMI have been well documented, the relationship between childhood region of residence and BMI in adulthood remains poorly understood. This study aimed to estimate secular trends in BMI among US adults and to examine these trends in relation to region of residence in childhood and adulthood. Using 16 waves of nationally representative data from The National Longitudinal Survey of Youth 1979 (n=12,686), the study examined the change in individuals' BMI over 25 years using random effects models. We found an independent positive association between years of residence in the South during childhood and adolescence (age 14), and secular trends in overweight during adolescence and adulthood (ß = .08, p =.05). In line with previous studies, the average BMI among men overall increases by 0.07~0.34 kg/m2 and the odds of being overweight increases multiplicatively by 3~12% (obese: 4~10%) over each birth cohort year. Among women, the average BMI increases by 0.14~0.21 kg/m2 and the odds of being overweight increases by -2~8% (obese: -6~10%). These increasing trends are significant for both genders among whites and among all races combined. The secular trend in BMI for respondents who resided in the South during childhood is elevated in comparison to the trend for other respondents, suggesting an independent association between childhood region of residence and trends in BMI during adulthood. This is the most precise and detailed epidemiologic study to date to examine secular trends in BMI among US residents in relation to regional differences.
