RESUMO
BACKGROUND/OBJECTIVES: The purpose of this study is to utilize an extended Theory of Planned Behavior in identifying predictors of exclusive breastfeeding intention and behavior among women in Kelantan, Malaysia. SUBJECTS/METHODS: A prospective cohort study was conducted, recruiting pregnant womenthrough two-stage cluster sampling. Their exclusive breastfeeding intention, attitude, perceived norm, perceived behavioral control and past behavior were obtained at baseline through interviewer-guided questionnaire. At one month after delivery, another interview was conducted to determine the two additional variables in the extended theory, which were their postpartum support and breastfeeding difficulty. The behavior, which was the actual duration of exclusive breastfeeding, was obtained from the second follow-up at six months. Pearson correlation and two hierarchical regression analyses were conducted. RESULTS: A total of 200 women completed the study follow-up. Their median intended exclusive breastfeeding duration was 4.0 (IQR 5) months, and the median actual duration was 1.0 (IQR 4) month. The Theory of Planned Behavior explained 51.0% of the variance in intention, with perceived behavioral control and attitude were the significant predictors. It also explained 10.0% of the variance in behavior, but the addition of postpartum support and breastfeeding difficulty increased the amount of explained variance in behavior by 6.0%. The significant predictors of exclusive breastfeeding behavior were intention, postpartum support and breastfeeding difficulty. CONCLUSION: The extended Theory of Planned Behaviorhad a good predictive ability in explaining exclusive breastfeedingintention and behavior. The women's intention to practice exclusive breastfeeding may be improved by improving their perceived behavioral control and attitude. Providing correct postpartum support and skills to handle breastfeeding difficulties after delivery will improve their exclusive breastfeeding behavior.
RESUMO
This study was aimed at identifying behavioural, normative and control belief influencing intention to practise exclusive breastfeeding among pregnant women in Malaysia. An interviewer-guided questionnaire assessing behavioural, normative and control belief was developed based on the findings elicited from focus group discussions. Intention referred to the respondent's intended duration of exclusive breastfeeding, which was measured in weeks. Bivariate correlational analysis, linear regression analysis and independent t test comparing intenders and non-intenders were conducted to identify the composite belief measures and individual beliefs significantly influencing intention. Composite measures of all the beliefs were significantly correlated with intention, but injunctive normative belief and behavioural belief were the only significant factors identified from linear regression analysis. The respondents agreed to comply with four referents of their mother, husband, nurses and mother-in-law. Non-intenders believed that those referents would oppose them practising exclusive breastfeeding for six months. The behavioural belief concerning difficulty to leave the infant significantly differentiated intenders from non-intenders. Exclusive breastfeeding promotion should include the woman's mother, husband and mother-in-law. Nurses should provide accurate and complete information related to breastfeeding practise. Providing support for women to continue the practise even though separated from their infants may improve their intention and practise of exclusive breastfeeding.
