“…The 1987 National Indonesia Contraceptive Prevalence Survey revealed that household economic level, language, place of delivery, type of birth attendant, mother's education, mother's occupational experience, spouse's education, spouse's occupation, mother's age at the time of birth, parity, child's sex, and ''wantedness'' of pregnancy were associated with duration of breastfeeding. 10 Another more recent study also used secondary data of the national demographic survey and found that mother's work, first children, low antenatal clinic visits, and higher proportion of richest households were associated with non-exclusive breastfeeding. 7 Compared with those studies, our findings are different and more pertinent, which may have been caused by differences in design, time setting, subject characteristics, and different determinants studied.…”
