Hypertensive Disorders during Pregnancy and Anthropometric Measurement of Children up to 7 Years of Age: The Hokkaido Birth Cohort Study in Japan.

ABSTRACT: Hypertensive disorders during pregnancy (HDP) increase the risk of offspring with a low birth weight, preterm birth and small-for-gestational age; however, evidence of the anthropometric measurements during early childhood remains limited. We aimed to understand the associations between maternal HDP and anthropometric measurements of children aged up to seven years in a Japanese cohort. In total, 20,926 mother-infant pairs participated in the Hokkaido Study on Environment and Children's Health, Japan, from 2002 to 2013. Medical reports were used to confirm HDP exposure, while weight, height, height z score, and weight z score were the outcomes. The prevalence of HDP in the study population was 1.7%. The birth height of male children born to HDP mothers was smaller as compared to those born to non-HDP mothers. When adjusted with covariates, the linear regressions showed significant changes in birth weight (β: -79.3; 95% confidence interval [CI]: -154.8, -3.8), birth height (-0.67; 95% CI: -1.07, -0.26), weight at seven years (1.21; 95% CI: 0.13, 2.29), and weight gain between four and seven years (1.12; 95% CI: 0.28, 1.96) of male children exposed to HDP. Differences were more significant in male children than female. Our study showed that despite low birth weight, male children exposed to HDP caught up with their growth and gained more weight by seven years of age compared with male children not exposed to HDP, whereas no such differences were observed in female children; however, this finding requires replication.

Project description:BackgroundPregnancy complications, such as gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP), affect a significant proportion of women in Australia, with long-term implications for cardiovascular disease (CVD) risk. Despite existing preventive measures, participation in ongoing health monitoring remains low. This study aims to explore women's preferences and experiences regarding preventive healthcare after GDM and HDP, and to identify their unanswered questions about the association between these conditions and future CVD risk.MethodsA participatory, qualitative approach was adopted, involving a Lived Experience Expert Group (LEE Group) to plan, conduct, and interpret focus groups with women who had experienced either GDM or HDP. Participants were recruited through health consumer and community organisations and took part in two focus groups conducted via Zoom. The focus groups involved a stimulus presentation about CVD and GDM or HDP, facilitated group discussion about participants' health and healthcare since their pregnancy, and Nominal Group Technique to prioritise participants' questions about their CVD risk. Focus groups were audio recorded and transcripts from each group were analysed thematically. Synthesised Member Checking was used to verify the trustworthiness of findings.ResultsTwelve women participated in the focus groups, with distinct themes emerging from the GDM and HDP focus groups. Participants were previously unaware of the association between their pregnancy complication and increased risk of future CVD and wished to know more. Three themes were generated from the GDM focus groups: 'a distressing diagnosis'; 'degrees of diabetes'; and 'balancing motherhood and self-care'. Two themes were generated from the HDP focus groups: 'women's concerns were dismissed' and 'wanting follow up at the right time and with the right person'. The 'top ten' questions from each group focussed on improving maternity care, preventing CVD, and (for the HDP group) concerns beyond CVD.ConclusionsWomen's capacity to engage in preventive health after GDM and HDP is influenced by their maternity care experiences and the accessibility of primary care pathways. Future interventions should focus on improving woman-centred maternity care, ensuring seamless transitions to primary care, and addressing the social determinants of health for new mothers.
