Background: Low birth weight (LBW) remains a public health problem in many developing countries. The purpose of this study was to determine biopsychosocial factors associated with low birth weight in East Lombok, Nusa Tenggara Barat.

Subjects and Method: A cross sectional study was conducted in 25 community health centers in Lombok, Nusa Tenggara Barat, from September to November 2018.A sample of 200 infants was selected by random sampling. The dependent variable was low birth weight. The in­de­pen­dent variables were maternal age, maternal education, mater­nal employment status, fa­mily in­come, prenatal stress, maternal nutritional status, smoke exposure, social support, and so­­­cial ca­pital. Data on LBW were obtained from the medical record. The data were collected by questionnaire and analyzed by a mul­tiple logistic regression.

Results:Maternal age <20 or ≥35 years (b= 2.60; 95% CI= 0.96to 4.25; p= 0.002), prenatal stress (b= 1.30; 95% CI= 0.01to 2.57; p= 0.048),and smoke exposure(b= 1.57; 95%CI= 0.37to 2.76; p= 0.010) increased the risk of LBW. High maternal education (b= -1.38; 95% CI= -2.60 to -0.15; p= 0.027), high family income (b= -1.32; 95% CI= -2.61to -0.04; p= 0.072), strong social support (b= -1.50; 95% CI= -2.92to-0.09; p= 0.036), good maternal nutritional status (b= -2,01; 95% 95%CI= -3.26to -0.76 ; p= 0.002),and social capital (b= -1.45; 95% CI= -2.82to -0.08; p= 0.038) decreased the risk of LBW. Maternal employment status decreased the risk of LBW but it was statistically non-significant (b= -1.43; 95% CI= -2.98to 0.12; p= 0.072).

Conclusion:Maternal age, prenatal stress, and smoke exposureincrease the risk of LBW. High maternal education, high family income, strong social support, maternal nutrition status,and socialcapital decrease the risk of LBW. Maternal employment status decreases the risk of LBW but it is statistically non-significant.
