Chronic Maternal Depression Is Associated with Reduced Weight Gain in Latino Infants from Birth to 2 Years of Age
BACKGROUND: Latino children are at increased risk for mirconutrient deficiencies and problems of overweight and obesity. Exposures in pregnancy and early postpartum may impact future growth trajectories. OBJECTIVES: To evaluate the relationship between prenatal and postnatal maternal depressive symptoms experienced in pregnancy and infant growth from birth to 2 years of age in a cohort of Latino infants. METHODS: We recruited pregnant Latina mothers at two San Francisco hospitals and followed their healthy infants to 24 months of age. At 6, 12 and 24 months of age, infants were weighed and measured. Maternal depressive symptoms were assessed prenatally and at 4-6 weeks postpartum. Women who had high depressive symptoms at both time periods were defined as having chronic depression. Logistic mixed models were applied to compare growth curves and risk for overweight and underweight based on exposure to maternal depression. RESULTS: We followed 181 infants to 24 months. At 12 and 24 months, respectively, 27.4% and 40.5% were overweight, and 5.6% and 2.2% were underweight. Exposure to chronic maternal depression was associated with underweight (OR = 12.12, 95%CI 1.86-78.78) and with reduced weight gain in the first 2 years of life (Coef = -0.48, 95% CI -0.94-0.01) compared with unexposed infants or infants exposed to episodic depression (depression at one time point). Exposure to chronic depression was also associated with reduced risk for overweight in the first 2 years of life (OR 0.28, 95%CI 0.03-0.92). CONCLUSIONS: Exposure to chronic maternal depression in the pre- and postnatal period was associated with reduced weight gain in the first two years of life and greater risk for failure to thrive, in comparison with unexposed infants or those exposed episodically. The infants of mothers with chronic depression may need additional nutritional monitoring and intervention
Maternal Postpartum Distress and Childhood Overweight
OBJECTIVE: We investigated associations between maternal postpartum distress covering anxiety, depression and stress and childhood overweight. METHODS: We performed a prospective cohort study, including 21,121 mother-child-dyads from the Danish National Birth Cohort (DNBC). Maternal distress was measured 6 months postpartum by 9 items covering anxiety, depression and stress. Outcome was childhood overweight at 7-years-of age. Multiple logistic regression analyses were performed and information on maternal age, socioeconomic status, pre-pregnancy BMI, gestational weight gain, parity, smoking during pregnancy, paternal BMI, birth weight, gestational age at birth, sex, breastfeeding and finally infant weight at 5 and 12 month were included in the analyses. RESULTS: We found, that postpartum distress was not associated with childhood risk of overweight, OR 1.00, 95%CI [0.98-1.02]. Neither was anxiety, depression, or stress exposure, separately. There were no significant differences between the genders. Adjustment for potential confounders did not alter the results. CONCLUSION: Maternal postpartum distress is apparently not an independent risk factor for childhood overweight at 7-years-of-age. However, we can confirm previous findings of perinatal determinants as high maternal pre-pregnancy BMI, and smoking during pregnancy being risk factors for childhood overweight
Childbirth and consequent atopic disease: emerging evidence on epigenetic effects based on the hygiene and EPIIC hypotheses
Background: In most high and middle income countries across the world, at least 1:4 women give birth by cesarean
section. Rates of labour induction and augmentation are rising steeply; and in some countries up to 50 % of laboring
women and newborns are given antibiotics. Governments and international agencies are increasingly concerned about
the clinical, economic and psychosocial effects of these interventions.
Discussion: There is emerging evidence that certain intrapartum and early neonatal interventions might affect the
neonatal immune response in the longer term, and perhaps trans-generationally. Two theories lead the debate in this
area. Those aligned with the hygiene (or ‘Old Friends’) hypothesis have examined the effect of gut microbiome colonization
secondary to mode of birth and intrapartum/neonatal pharmacological interventions on immune response and epigenetic
phenomena. Those working with the EPIIC (Epigenetic Impact of Childbirth) hypothesis are concerned with the effects of
eustress and dys-stress on the epigenome, secondary to mode of birth and labour interventions.
Summary: This paper examines the current and emerging findings relating to childbirth and atopic/autoimmune
disease from the perspective of both theories, and proposes an alliance of research effort. This is likely to accelerate
the discovery of important findings arising from both approaches, and to maximize the timely understanding of the
longer-term consequences of childbirth practices

Maternal smoking during pregnancy and offspring overweight: is there a dose-response relationship? An individual patient data meta-analysis
Published online: 28 February 2018Background/objectives: A number of meta-analyses suggest an association between any maternal smoking in pregnancy and offspring overweight obesity. Whether there is a dose–response relationship across number of cigarettes and whether this differs by sex remains unclear. Subject/methods: Studies reporting number of cigarettes smoked during pregnancy and offspring BMI published up to May 2015 were searched. An individual patient data meta-analysis of association between the number of cigarettes smoked during pregnancy and offspring overweight (defined according to the International Obesity Task Force reference) was computed using a generalized additive mixed model with non-linear effects and adjustment for confounders (maternal weight status, breastfeeding, and maternal education) and stratification for sex. Results: Of 26 identified studies, 16 authors provided data on a total of 238,340 mother–child-pairs. A linear positive association was observed between the number of cigarettes smoked and offspring overweight for up to 15 cigarettes per day with an OR increase per cigarette of 1.03, 95% CI = [1.02–1.03]. The OR flattened with higher cigarette use. Associations were similar in males and females. Sensitivity analyses supported these results. Conclusions: A linear dose–response relationship of maternal smoking was observed in the range of 1–15 cigarettes per day equally in boys and girls with no further risk increase for doses above 15 cigarettes.Lucia Albers, Christina Sobotzki, Oliver Kuß, Teresa Ajslev, Rosangela FL Batista, Heloisa Bettiol, Bernard Brabin, Stephen L Buka, Viviane C Cardoso, Vicki L Clifton, Graham Devereux, Stephen E Gilman, Luke E Grzeskowiak, Joachim Heinrich, Sandra Hummel, Geir W Jacobsen, Graeme Jones, Gibby Koshy, Camilla Schmidt Morgen, Emily Oken, Tomas Paus, Zdenka Pausova, Sheryl L Rifas-Shiman, Andrea J Sharma, Antônio AM da Silva, Thorkild IA Sørensen, Elisabeth Thiering, Stephen Turner, Torstein Vik, Rüdiger von Krie

Physical and psychosocial safety climate scales: psychometric evidence and invariance measurement in a Portuguese sample
Accident prevention is one of the key rules for workplace safety, and the safety climate has been linked to the possibility of influencing not only the safety behavior of workers but also the occurrence of accidents. Thus, this study aims to present the psychometric evidence of the physical and psychosocial safety climate scales in a Portuguese sample. From a sample of 844 participants, 505 men and 339 women, aged between 17 and 68 years (M = 37.09, SD = 10.57), the results show that the one-factor solution yielded the best fit to the data with acceptable reliability in both scales. The invariance measure between professions was only observed in the psychosocial safety climate scale, thus alerting to the susceptibility to different professional populations of the physical safety climate scale. Understanding the safety climate is critical to reducing occupational disease, injuries and accidents, and further study should deepen the psychometric qualities of both scales.info:eu-repo/semantics/publishedVersio
