Effects of a Comic Booklet Intervention Aimed at Preventing Second-Hand Smoke Exposure for Pregnant Women in Indonesia: A Randomised Controlled Trial.

Second-hand smoke (SHS) has adverse effects for pregnant women and foetuses. This controlled and randomized clinical trial evaluated the efficacy of a comic booklet intervention in promoting SHS avoidance among pregnant women and appropriate smoking behaviours among their male partners. We allocated 140 couples to the experimental group (EG), who received the comic booklet and a reminder sticker, and 146 couples to the control group (CG), who received usual care. The primary outcomes were women's self-reported SHS exposure and their male partners' smoking behaviours. Secondary outcomes included knowledge and awareness of SHS. Independent t-tests revealed that three months post-intervention, more male partners in the EG had appropriate self-reported smoking behaviours with a small effect size (Cohen's d = 0.35, 95% CI [0.08, 0.62], p-value = 0.01). Significantly more pregnant women in the EG recognised their partners' appropriate smoking behaviours with a nearly middle effect size (Cohen's d = 0.43, 95% CI [0.16, 0.70], p-value ≤ 0.01). Cues to action showed a significant difference between groups with a small effect size (Cohen's d = 0.36, 95% CI [0.09, 0.63], p-value = 0.01), as evaluated by male partners. These findings suggest that the comic booklet intervention might be effective against SHS exposure by providing several cues to action through knowledge and awareness of SHS.

An exploratory test of a couples-based condom-use intervention designed to promote pleasurable and safer penile-vaginal sex among university students.

Objective: Dual use of male condoms and female contraceptives is widely advocated for unplanned pregnancy prevention, yet college students often neglect condoms. This feasibility and acceptability study assessed the efficacy of a self-guided home-based condom-promotion intervention among college students in heterosexual relationships. Participants: Fifty-nine couples who had been together at least 30 days and had penile-vaginal sex at least twice weekly. Methods: Assessments were done at baseline and 6 months later. Outcomes were frequency of condom-unprotected penile-vaginal sex and four psychosocial mediators of condom use. Results: Frequency of unprotected penile-vaginal sex decreased over time. Several corresponding psychosocial mediators showed change, particularly among women. Using actor-partner interdependence modeling, men's increase in condom use was associated with an increase in women's sexual pleasure. Conclusion: Findings support implementation of a brief, self-guided, home-based condom-use intervention that could lower incidence of unplanned pregnancy and STIs among heterosexually active college students.

An mHealth intervention to prevent postnatal smoking relapse: The RESPREMO study protocol.

Up to 70% of women who quit smoking relapse after birth, usually within 3 months postpartum. The wide adoption of mobile technologies, especially smartphones, in recent years in low- and middle-income countries (LMICs) offers the possibility of low-cost, novel, and innovative mobile phone-based interventions for smoking relapse prevention. This study presents the protocol of the RESPREMO clinical trial for postnatal smoking relapse prevention for enrolled women, who recently gave birth and quit tobacco smoking before or during pregnancy, and their life partners. This work relies on data collected in two of the largest government-owned obstetrics and gynecology clinics in Cluj-Napoca, Romania. Seventy-five couples were randomized into one of three groups: a) 24 couples were allocated to the first intervention group and asked to install and use the xSmoker app; b) 26 couples were randomized to the second intervention group, who, in addition to the use of the xSmoker app, received text messages with content focused on motivation, problem solving, and dyadic efficacy; and c) 25 couples were randomized into a control group. Several measures of engagement with the xSmoker app were assessed, including duration of app use, the frequency of utilizing the tool to calculate savings from quitting, number of app-delivered challenges accepted by users, and number of app-delivered cessation and abstinence tips. If effective, RESPREMO is expected to have a sustainable impact on the prevention of postnatal relapse tobacco smoking with positive effects for both the mother and the newborn. The implications are beyond tobacco control, and relevant to the design and implementation of other mHealth behavioral interventions focused on the pregnancy and reproductive years in general.

A couples-focused intervention for smoking cessation during pregnancy: The study protocol of the Quit Together pilot randomized controlled trial.

Tobacco smoking remains the leading global cause of preventable disease and death. Preconception and pregnancy smoking are high in Central and Eastern Europe. Quit Together is a partnership between a US university and a Romanian university, obstetrics and gynecology clinics in Romania, and other community partners in Romania. The objective of the Quit Together pilot study is to adapt, enhance and test the implementation feasibility and initial efficacy of an evidence-based pregnancy and postnatal couple intervention for smoking cessation in Romania. Quit Together builds on the Motivation and Problem Solving (MAPS) approach, enhanced by targeting the couples' smoking behavior and focusing on dyadic efficacy for smoking cessation. The study is an ongoing randomized controlled trial of 120 Romanian pregnant smokers and their partners. Participants are randomized to: 1) an intervention arm consisting, typically, of up to 8 prenatal and postnatal telephone counseling calls for the women and 4 for their partners, combining motivational strategies and problem-solving/coping skills to encourage the woman to quit smoking and the partner to support her decision; and 2) a control arm (usual care). The primary outcome is maternal biochemically verified smoking abstinence at 3 months postpartum. Quit Together has the potential to identify effective strategies to increase maternal smoking cessation during pregnancy and smoking abstinence after birth. If effective, Quit Together is expected to have a sustainable positive impact on the health of the child, mother and partner, and potentially reduced health system costs.

The male factor: Outcomes from a cluster randomized field experiment with a couples-based HIV prevention intervention in a South African township.

BACKGROUND: This study examined the effects of the Couples Health CoOp intervention on heavy drinking, condom use, and HIV incidence. METHODS: Thirty neighborhoods from one South African township were cluster randomized into three intervention arms: Couples Health CoOp (CHC), Women's Health CoOp/Men's Health CoOp (WHC/MHC), or a comparison arm. We recruited 290 men from informal drinking establishments who reported drinking alcohol regularly. We also recruited their main heterosexual sex partners. RESULTS: At 6-month follow-up, men in the CHC arm were less likely to report heavy drinking (OR 0.47, 95% CI: 0.25, 0.90) and were more likely to report consistent condom use during the past month (OR 2.66, 95% CI: 1.23, 5.76) than men in the comparison arm. At baseline, 26% of women and 13% of men were HIV-infected; at 6-month follow-up, 16 females and 5 males had seroconverted. HIV incidence was significantly lower among women in the CHC arm (IRR 0.22, 95% CI: 0.04, 1.01) than in the WHC/MHC arm. CONCLUSIONS: A couples-based intervention focusing on intersecting risks for HIV can improve biobehavioral outcomes, underscoring the importance of engaging couples together in HIV prevention.

A couple-focused intervention to prevent postnatal smoking relapse: PRISM study design.

BACKGROUND: Maternal smoking is one of the most modifiable factors with clear adverse effects for the fetus and the entire family. Addressing the dearth of pregnancy smoking interventions with partner support, PRISM (Prevent Relapse In SMoking) is a partnership between a research institution and the two largest state-owned obstetrics and gynecology clinics in Cluj-Napoca, Romania. The study will assess the efficacy of a couple-focused telephone-counseling program to prevent smoking relapse among mothers who quit smoking closely before or during pregnancy. METHODS/DESIGN: The intervention is a program for couples based on motivational interviewing delivered over the phone after birth. The study is an ongoing randomized controlled trial of 250 Romanian women recruited soon after childbirth, who quit smoking in the six months before pregnancy or no later than the end of the first pregnancy trimester and remained abstinent (which was biochemically verified) until delivery. Participants were randomized to: (1) a control arm (usual care); and (2) an intervention arm consisting of up to 4 postnatal counseling calls for mothers and their partners using motivational interviewing to encourage the woman to remain smoke-free and the partner to support her decision. The primary outcome is maternal smoking abstinence at 6 months postpartum (biochemically verified). DISCUSSION: PRISM has the potential to identify strategies to reduce maternal postnatal relapse and increase partner quitting. If successful, the program may be an effective method to prevent and reduce smoking, which may lead to improved child, mother, and partner health both in the short and the long term.
