Evaluating the diagnostic properties of the Whooley questionnaire as a case-finding instrument for depression among Chinese women during and after pregnancy.

Purpose: There is a rising prevalence in undetected perinatal depression in many countries, more effort in screening and early identification of perinatal depression is needed. While the Whooley questionnaire is the recommended case-finding strategy for perinatal depression, there is no validated Chinese version. The aim was to evaluate the diagnostic accuracy and stability of the translated Chinese Whooley questionnaire against gold standard measurement during and early after pregnancy.Materials and Methods: This observational study recruited 131 pregnant women from an antenatal clinic in Hong Kong from September 2019 to May 2020. We translated the Whooley questionnaire in Chinese and evaluated self-reported responses against an interviewer-assessed diagnostic standard (DSM-IV criteria) in 107 women at 26-28 gestational weeks. We calculated sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio, with DSM-IV diagnosis as the gold standard.Results: The Chinese Whooley questions had a sensitivity of 79% (95% CI 54.4-93.9), a specificity of 97% (95% CI 90.4-99.3), a positive likelihood ratio of 23.2 (95% CI 7.4-72.1) and a negative likelihood ratio of 0.2 (95% CI 0.1-0.5) in identifying perinatal depression.Conclusion: The translated Chinese Whooley questionnaire has an acceptable diagnostic accuracy in identifying perinatal depression. It can be implemented in health services among Cantonesespeaking Chinese population.

Feasibility, acceptability, and potential efficacy of an innovative postnatal home-based breastfeeding peer support programme in Hong Kong: a feasibility and pilot randomised controlled trial.

BACKGROUND: As suggested by the World Health Organization, breastfeeding peer support is being introduced worldwide to support women's breastfeeding needs. Evidence has shown that when such support is offered to women, the duration and exclusivity of breastfeeding is increased. We developed an innovative home-based intervention to sustain exclusive breastfeeding in Hong Kong. However, potential barriers must be addressed before a full randomised controlled trial (RCT) is conducted. The aim of this study was to determine the feasibility of a breastfeeding support programme with home-based visits from peer supporters over a six month period among postpartum Chinese women in Hong Kong. METHODS: We conducted a feasibility and pilot randomised controlled trial. Twenty primiparous women intending to breastfeed their healthy term singleton infant were recruited from a hospital in Kowloon, Hong Kong between February and March 2019. Participants were randomly allocated to the intervention or control group. Participants in the intervention group received five home-based visits with a peer supporter over a six month period, as well as standard care, whereas participants in the control group received standard care only. We assessed feasibility, compliance, and acceptability of the breastfeeding peer support programme. Other outcomes assessed were breastfeeding self-efficacy, duration, and exclusivity. RESULTS: It was feasible to recruit and train existing peer supporters, and peer supporters were able to deliver the intervention, which was acceptable to women, but rates of stopping the intervention and loss to follow-up were high. There was higher retention seen within the first month. Women interviewed at the end of the study reported that the intervention was positive. The cessation risk of any, and exclusive breastfeeding were not statistically different between the intervention and control groups. CONCLUSIONS: This study provided valuable information on feasibility of the trial design and intervention. Modifications to the intervention, such as targeting women with lower breastfeeding self-efficacy, or combining home visits with technology and telephone follow-up may be more appropriate in a larger trial. Implementing the programme early during the antenatal phase and tailoring peer support to most appropriately sustain exclusive breastfeeding and other feeding modes should be incorporated in a future home-based peer support arm.

Exposure to baby-friendly hospital practices and mothers' achievement of their planned duration of breastfeeding.

BACKGROUND: Both breastfeeding intentions and exposure to baby-friendly hospital practices were found to be associated with a longer duration of breastfeeding. This study aims to examine the effect of exposure to baby-friendly hospital practices on mothers' achievement of their planned duration of breastfeeding. METHODS: A total of 1011 mother-newborn pairs from the postnatal units of four public hospitals in Hong Kong were recruited. Sociodemographic data and breastfeeding intention data were collected via self-report questionnaires during the postnatal hospitalization and exposure to Baby-Friendly hospital practices were assessed through hospital records and maternal self-report. Breastfeeding status after hospital discharge was assessed through telephone follow-up for up to 12 months postnatal, or until participants were no longer breastfeeding. RESULTS: Only 55% (n = 552) of study participants achieved their intended duration of breastfeeding. Participants with higher socioeconomic status, previous breastfeeding experience, and those who had lived in Hong Kong for less than 5 years, were more likely to achieve their planned duration of breastfeeding. Among baby-friendly hospital practices, feeding only breast milk during the hospitalization and providing information about breastfeeding support on discharge were associated with participants' achieving their individual breastfeeding intentions. After adjustment, when compared with women who experienced onebaby-friendly practice, participants who experienced six baby-friendly hospital practices were significantly more likely to achieve their planned duration of breastfeeding (adjusted odds ratio = 8.45, 95% confidence interval 3.03-23.6). CONCLUSIONS: Nearly half of participants did not achieve their planned breastfeeding duration. Exposure to baby-friendly hospital practices, especially in-hospital exclusive breastfeeding and providing breastfeeding support information upon hospital discharge may help more mothers to achieve their individual breastfeeding goals.
