Interventions designed to limit gestational weight gain: a systematic review of theory and meta-analysis of intervention components

摘要: Limiting gestational weight gain (GWG) to recommended levels is important optimize health outcomes for mother and baby. Surprisingly, a recent review revealed that theory-based interventions limit GWG were less effective than did not report theory-base; however, strict criteria used identify theory-informed studies. We extended this others by systematically evaluating the theories of behaviour change informing using generalized psychology perspective, meta-analysing techniques reported in interventions. Interventions designed searched health, nursing databases. Papers reporting an underpinning theory identified CALO-RE taxonomy was determine individual techniques. Nineteen studies inclusion. Eight informed theory; six favourable effects on GWG. Overall, based as non-theory-based at limiting Furthermore, provision information, motivational interviewing, behavioural self-monitoring providing rewards contingent successful appear be key strategies when intervening Combining these with dietary may most effective. Future research should focus determining exact combination techniques, or which theories, are useful
