PMID 36264692WHAT IT FOUND
Pregnant women's confidence in breastfeeding and perceived social pressure predicted intention to breastfeed exclusively.
The extended model explained 46% of differences in intention scores, but social support did not directly predict intention.
Key findings
01The extended model explained 46% of differences in intention, compared with 37% for the original model.
02In the extended model, self-efficacy, subjective norms, and perceived behavioral control directly predicted intention, while attitude and social support did not directly predict it.
03The study measured exclusive breastfeeding intention, not actual exclusive breastfeeding behavior.

What it does not show
The study measured intention only, not actual exclusive breastfeeding behavior. The design was cross-sectional, so it cannot show cause or change over time. Participants were pregnant nulliparous women in Kerman, Iran, and 90% were housewives, so the findings may not apply elsewhere. The extended model explained 46% of differences in intention. Social support and attitude were correlated with intention but did not directly predict it in the extended model.
Declared interests
The study was supported by Rafsanjan University of Medical Sciences.
The easy way to misread this
Do not conclude that improving self-efficacy or social support will increase exclusive breastfeeding; this study measured intention only, not behavior, and it did not test an intervention.
