Lifestyle, psychological stress, and incidence of adolescent constipation: results from the Toyama birth cohort study

Abstract Background We aimed to clarify the predisposing factors for adolescent constipation in a longitudinal study, because while factors associated with childhood constipation have been reported, prospective studies on the incidence of constipation are lacking. Methods We enrolled 5540 adolescents aged 12 to 13 years from the Toyama Birth Cohort Study—a community-based prospective study examining children’s health. The incidence of constipation, defined as bowel movement frequency of less than once every 2 days, was surveyed during the three-year period from baseline (grade 4) to follow-up (grade 7). Multivariate logistic regression analyses were performed to explore the association between the incidence of adolescent constipation and their lifestyle variables. Results A total of 261 adolescents (4.7%) developed constipation during the three-year period. Female sex (odds ratio [OR] = 2.62,) overweight (OR = 0.60), and infrequent intake of fruits (OR = 1.50) at baseline were associated with the incidence of constipation. Furthermore, factors related to lifestyle changes and psychological status such as skipping breakfast (OR = 1.73), becoming physically inactive (OR = 1.55), and being persistently irritated (OR = 1.80) were significantly associated with the incidence of constipation. Conclusion Our prospective study demonstrated that female sex, insufficient fruit intake, and deteriorating lifestyles such as skipping breakfast and becoming inactive during the 3-year period were associated with the incidence of adolescent constipation. Beyond anecdotal, maintaining a healthy lifestyle is recommended to reduce the incidence of adolescent constipation.

The Impact

Abstract Background Cleft lip and/or palate (CL/P) is among the most prevalent congenital birth defects. They negatively affect maternal psychological status and may consequently result in higher prevalence of child maltreatment. However, the association of CL/P births with bonding disorders still remains unclear. To address this question, we examined the impact of CL/P birth on mother-to-infant bonding, using the nationwide birth cohort study, Japan Environment and Children's Study. Methods This study was conducted as a nationwide birth cohort study of the Japan environment and children’s study (JECS), an ongoing nationwide birth cohort study in Japan. 104,065 of foetuses in fifteen regional centres in JECS were enrolled. Finally, the participants consisted of 79,140 mother-infant pairs, of which 211 mothers with CL/P infants were included in our analyses. Results First, no increased risk of bonding disorders was observed among all the mothers with CL/P births (odds ratio [95% CI]; 0.97 [0.63-1.48], p = 0.880), and advanced maternal age or multiple parity would adversely affect the associations between bonding disorders and CL/P births, respectively. Thus, after stratification with a combination of maternal age and parity, a significant association of CL/P birth with bonding disorders was found only among advanced-age multiparae (OR [95% CI] = 2.51 [1.17-5.37], p = 0.018), but it was weakened after additional adjustment for maternal depression. Conclusion CL/P birth may increase the risk of bonding disorders among advanced-age multiparae possibly through maternal depression. This finding provides valuable information for the provision of multidisciplinary cleft care.
