Maternal periodontal disease as a significant risk factor for low birth weight in pregnant women attending a secondary care hospital in South India: A Case-control study.

Context: Periodontal disease (PD) is a common infection in the community; however, its relationship with low birth weight (LBW) has not been well‑established. Aims: The aim was to determine the association between maternal PD and LBW. Settings and Design: A case–control (1:1) study. Materials and Methods: The study population comprised of women who delivered at the hospital during the study period (September 2011 to February 2012).Women between 18 and 35 years of age, who delivered singleton, live infants during study period with at least 18 teeth were enrolled. Those with pregnancy induced hypertension, gestational diabetes, blood‑borne viral infections, periodontal treatment within the past 6 months and valvular heart disease were excluded. Control population was parity matched to the cases. Statistical Analysis Used: Chi‑square test, t‑test and univariant and multivariant logistic regression were used to analyze various study findings, and level of significance was set at 5% (P < 0.05). Results: PD was independently associated with LBW (odds ratio: 4.94, 95% confidence interval: 1.03–23.65, P=0.045). Additionally, conventional risk factors such as maternal height (P=0.029), secondary schooling (<8 years of schooling) (P = 0.001), socio‑economic status (P = 0.046), type of family (joint) (P = 0.008), number of ante‑natal visits (P = 0.028) and gestational age at birth (<37 weeks) (P = 0.045) showed significant association with LBW. Conclusions: There seems to be an association between PD and LBW independent of conventional risk factors. Women who had PD were 5 times more likely to deliver LBW infants.

Domestic violence as a risk factor for infant and child mortality: A community-based case–control study from southern India.

Background. Violence against women may have an impact on infant and child mortality. We aimed to determine whether domestic violence is a risk factor for infant and child death. Methods. Eighty infant and child deaths (under 5 years of age) were identified from a central register of a comprehensive community health programme in rural southern India; controls were matched for age, gender and street of residence. Results. Domestic violence during the lifetime (OR 2.63, 95% CI 1.39–4.99), which was severe (OR 4.00, 95% CI 2.02–7.94) and during pregnancy (OR 5.69, 95% CI 2.03–15. 93) and father’s smoking status (OR 3.81, 95% CI 1.92–7.55) were significantly related to infant and child death while immunization being completed for age (OR 0.04, 95% CI 0.01–0.19) and having at least one boy child in the family (OR 0.29, 95% CI 0.14–0.59) were protective. These variables remained statistically significantly associated with outcome after adjusting for other determinants using conditional logistic regression. Conclusion. There is evidence for an association between domestic violence in mothers, and infant and child death.
