Maternal underweight and the risk of preterm birth and low birth weight: a systematic review and meta-analyses

“…Others maternal risk factors associated with an increased risk of a SGA neonate are maternal age ≥35 years and particulalry in women ≥40 years old [27], African American [28] or Indian/Asian ethnicity [29], nulliparity [30], social deprivation [31], body mass index (BMI) <20, BMI > 25 [32], alcohol intake [33], drug use (with cocaine use during pregnancy being the most significant) [34] and cigarette smoking [35]. Singleton pregnancies following IVF are also at increased risk for SGA [36].…”

Fetal growth restriction (FGR) diagnosed before 32 weeks is identified by fetal smallness associated with Doppler abnormalities and is associated with significant perinatal morbidity and mortality and maternal complications. Recent studies have provided new insights into pathophysiology, management options and postnatal outcomes of FGR. In this paper we review the available evidence regarding diagnosis, management and prognosis of fetuses diagnosed with FGR before 32 weeks of gestation.

“…The prevalence of underweight remains high (20–40%) among Asian women, despite steady declines over the past decade [4]. Underweight should be managed in Asian women, as low body weight during childbearing years has been associated with health problems affecting both infants and mothers, including preterm birth [5], low birth weight [6,7] and retarded growth during childhood [8]. Additionally this can lead to poor psychological health [9], increased risks of chronic diseases in later life [10] and early mortality [11].…”

Background: The prevalence of underweight is high among women in Asian countries, despite nutritional changes in the region. Previous studies have demonstrated independent associations between female body weight, marital status and economic status. However, few studies have investigated possible interaction between marital and economic status in relation to Asian women’s body weight. Objective: This study aimed to test associations between household wealth, marital status and underweight among women living in the Quoc Oai district of Vietnam and to identify wealth–marital status interaction in relation to body weight in these women. Methods: Data from 1087 women aged 19–60 years were collected via a baseline community survey conducted in the Quoc Oai district of Hanoi, Vietnam, in 2016. Underweight was defined using an Asian-specific body mass index cut-off (<18.5 kg/m2). Marital status was dichotomized into ‘never married’ and ‘ever married.’ Economic status was measured using household wealth index quintiles. Multivariable logistic regressions tested association between wealth and underweight after adjusting for marital status and other confounders. An interaction term (wealth index*marital status) was fitted to determine whether the association between wealth and body weight is modified by marital status. Results: Our results show that underweight was independently associated with a wealth status (odds ratio [OR]: 0.88, 95% confidence interval [CI]: 0.79–0.98, p = 0.026) and ever-married status (OR: 0.50, 95% CI: 0.34–0.75, p = 0.002). A significant interaction effect (OR: 0.67, 95% CI: 0.50–0.90, p = 0.010) indicated that wealthy married women were less likely to be underweight, whereas wealthy never-married women were more likely to be underweight. Conclusions: Our results suggest that the interaction between wealth and marital status has divergent effects on underweight among Asian women. Interventions to reduce underweight among Asian women should simultaneously consider economic and marital status.

Maternal underweight and the risk of preterm birth and low birth weight: a systematic review and meta-analyses

Abstract: In this systematic review and meta-analyses, we determined that singletons born to underweight women have higher risks of PTB (overall, spontaneous and induced) and LBW than those born to women with normal weight.
