Huang 2011.

Methods	Randomised controlled trial. Using a randomised table, the researcher assigned pregnant women to the control group or to 1 of the 2 intervention groups.
Participants	128 women aged18 years or older, without cognitive impairment or psychiatric illness, able to speak and read Chinese, not participating in another study, and planning to give birth at the study site. All participants were recruited during pregnancy.
Interventions	Intervention: intervention began 24–48 hours after birth and extended to 6 months postpartum. The intervention was delivered at bedside in the obstetric units and during regularly scheduled clinic visits by a nurse. The nurse discussed with each participant how to design an individualised dietary and physical activity education plan based on the participant’s baseline information. The plan consisted of 1 primary counselling session, 1 brochure and 2 booster sessions at 6 weeks postpartum and 3 months postpartum. Control: usual care plus participation in face‐to‐face discussions in the health education room with nurse educators about individual concerns, e.g. sexual life during pregnancy, preparation for breastfeeding, birth and first signs of labour. Trial duration: medium‐term.
Outcomes	Weight retention at 6 months postpartum. Other outcomes not considered in this review: health‐promoting behaviour, self‐efficacy, body image and social support.
Notes	The study did not contribute data for the statistical analysis. The study aimed at examining the effect of individual counselling about diet and physical activity among child‐bearing women during 2 periods: from pregnancy through to 6 months postpartum, and from birth through to 6 months postpartum. Only the second arm (intervention initiated during postpartum) was considered in this review. In total, 240 women were randomised and 51 women (16 in the control ; 16 in the postpartum intervention and 16 in the pregnancy intervention) who dropped out were not statistically different in age, parity, employment, education or BMI.
Risk of bias
Bias	Authors' judgement	Support for judgement
Adequate sequence generation	Low risk	Randomisation using a random‐number table.
Allocation concealment	Unclear risk	No detail provided.
Blinding All outcomes	Unclear risk	No detail provided.
Incomplete outcome data addressed All outcomes	High risk	20% of loss to follow‐up (including data for the intervention groups considered in this review).
Free of selective reporting	High risk	Some outcomes of relevance were not described (e.g. weight loss).
Free of other bias	Unclear risk	Supported by a grant from the NationalScienceCouncil,Taiwan (NSC 93‐2314‐B‐182‐079). No mention of any research protocol published a priori. The characteristics of participants were not significantly different between groups at baseline.
