- 요약Background: Sleep disorders are associated with increased risks of the leading causes of death worldwide including cardiovascular disease, diabetes, and cancer. While the consequences of disordered sleep are well studied, its etiology remains unclear. An emerging body of evidence suggests chronic illnesses may have an intrauterine origin. Intrauterine exposure to poor maternal nutrition has been linked to obesity, a predictor of sleep disorders, in the offspring and grandoffspring. Nevertheless, no previous studies have assessed the intergenerational associations of maternal obesity and sleep disorders.Objectives: We assessed maternal (F1 generation) early pregnancy body mass index (BMI) as a risk factor for sleep disorders, sleep apnea (aim 1) and insomnia (aim 2), in the offspring (F2 generation). To consider intergenerational effects, we evaluated grandmaternal early pregnancy (F0 generation) BMI as a risk factor for sleep apnea in the grandoffspring (aim 3).Methods: Using population-based nationwide Swedish registers, we constructed two- and three-generation cohorts consisting of, respectively, 3,281,803 and 315,461 live-born singleton births born 1983-2015. In aims 1 and 2, we utilized the two-generation cohort to compare offspring (F2) sleep apnea and insomnia risk, respectively, through early adulthood by maternal (F1) early pregnancy BMI categories using Cox proportional hazards models to estimate hazard ratios with 95% confidence intervals (CI). To control for potential confounding by shared familial factors, we conducted sibling comparisons among 1,724,473 full siblings. In aim 3, the three-generation cohort was used to compare grandoffspring (F2) childhood sleep apnea risk by grandmaternal (F0) early pregnancy BMI categories. We evaluated the extent to which this association was mediated by maternal (F1) early pregnancy BMI using causal mediation analysis. To assess whether shared familial factors explained these associations, we estimated sleep apnea risk by categories of parental full sisters' (F1) BMI, a negative control exposure.Results: Maternal (F1) overweight or obesity were associated with increased risk of sleep apnea and insomnia in the offspring (F2), in a dose-response manner. Compared with women with normal BMI, adjusted HR (95% CI) of offspring sleep apnea for maternal BMI categories overweight, obesity class I, and obesity class II or III were, respectively, 1.14 (1.09, 1.19), 1.28 (1.20, 1.36), and 1.40 (1.27, 1.54). Corresponding HR (95% CI) with insomnia as the outcome were, respectively, 1.22 (1.14, 1.30), 1.60 (1.45, 1.77), and 2.11 (1.83, 2.45). Similarly, maternal and paternal grandmaternal (F0) early pregnancy overweight or obesity were positively related with childhood sleep apnea risk in the grandoffspring (F2); Compared with maternal grandmothers with normal BMI (18.5-24.9), adjusted HR (95% CI) of grandoffspring childhood sleep apnea for grandmaternal BMI categories overweight (BMI 25.0-29.9) and obesity (BMI ≥30.0) were, respectively, 1.23 (1.02, 1.50) and 1.59 (1.15, 2.19). Maternal (F1) obesity mediated 19% of the maternal grandmaternal (F0) overweight or obesity and grandoffspring (F2) sleep apnea association. Results could not be explained by shared familial factors.Conclusions: Gestational exposure to maternal overweight or obesity may be related to sleep disorder pathogenesis in both offspring and grandoffspring. Given positive trends of obesity in recent decades, maternal overweight and obesity could be an increasingly relevant point of intervention to mitigate the adverse effects of disordered sleep in current and future generations.
