Introduction Several studies have examined how the lockdown restrictions enforced to halt the spread of COVID-19 have affected children and adolescents’ movement behaviours, but there is a need to synthesise these findings. Therefore, we conducted this systematic review to examine the impact of COVID-19 lockdown on children and adolescents’ movement behaviours. Methods We searched eight databases and grey literature for relevant studies of all study designs; and conducted a narrative analysis of the results following synthesis without meta-analysis guidelines. We used appropriate tools to assess the risk of bias in quantitative and qualitative studies. We compared changes in physical activity, screen time and sleep duration and quality from before to during the COVID-19 lockdown. Results This review included 71 studies reporting data from 35 countries and territories, mostly from high-income economies. A majority of the studies used a cross-sectional design and had fair to poor-quality ratings. Most studies reported reduced physical activity, increased screen time and longer sleep hours among children and adolescents. Children and adolescents facing strict lockdowns saw a larger decline in physical activity and a sharper increase in screen time than those under mild restrictions. Conclusion COVID-19-related lockdowns were detrimental to children and adolescents’ movement behaviours, with stricter lockdowns tending to have a bigger impact. Children and adolescents under COVID-19 restrictions are likely to be less active, spend more time on screen, and sleep longer hours than before the lockdown. More studies from low-income and middle-income countries could provide a clearer picture of the impact. PROSPERO registration number CRD42021245924.

Objective To investigate the roles of mobile health, or mHealth, in the psychosocial health of pregnant women and mothers. Methods A systematic search was conducted in databases and grey literature including MEDLINE, Web of Science, CINAHL, PsycINFO, PsycARTICLES, Academic Search Complete, SocINDEX, Central Register of Controlled Trials, The Database of Abstracts of Reviews of Effects, NHS Economic Evaluation Database, Health Technology Assessment, UNICEF and WHO databases. Two searches were conducted to include original research articles published in English until 15 November 2021. Several tools were used to assess the risk of bias: revised Cochrane risk of bias tool for randomised trials, Risk of Bias in Non-randomized Studies of Interventions, National Heart, Lung, and Blood Institute quality assessment tool for cohort and cross-sectional studies, Critical Appraisal Skills Program checklist for qualitative studies and Mixed Methods Appraisal Tool for mixed-methods studies. Certainty of evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation approach. Due to the high heterogeneity and variability of the included studies, data synthesis was conducted narratively. Results 44 studies were included among 11 999 identified articles. Most studies reported mixed findings on the roles of mHealth interventions in the psychosocial health of pregnant women and mothers; mHealth improved self-management, acceptance of pregnancy/motherhood and social support, while mixed results were observed for anxiety and depressive symptoms, perceived stress, mental well-being, coping and self-efficacy. Furthermore, pregnant women and mothers from vulnerable populations benefited from the use of mHealth to improve their psychosocial health. Conclusions The findings suggest that mHealth has the potential to improve self-management, acceptance of pregnancy/motherhood and social support. mHealth can also be a useful tool to reach vulnerable pregnant women and mothers with barriers to health information and facilitate access to healthcare services. However, the high heterogeneity limited the certainty of evidence of these findings. Therefore, future studies should identify the context under which mHealth could be more effective.

Home-based records are paper or electronic records retained and used by mothers or caregivers to document the health services received for maternal, newborn, and child health. Little has been studied about the roles of these records on newborn and child health outcomes. Hence, we collated and summarized evidence concerning the roles of home-based records in improving newborn and child health. We conducted a systematic search in several databases: MEDLINE, Web of Science, CINAHL, PsycINFO, PsycARTICLES, Academic Search Complete, SocINDEX, CENTRAL, DARE, NHS EED, HTA, J-STAGE, Ichushi, and gray literature. We included original research articles of all study designs published in English or Japanese until January 2020. Owing to heterogeneity across the outcomes of included studies, we conducted a narrative synthesis. We included 55 studies (23 in Japanese) among 14,017 identified articles. We identified the following roles of home-based records on newborn and child health: promoted newborn/childcare seeking, improved knowledge and practices of newborn/childcare, encouraged home care for childhood illnesses, reduced child mortality and morbidity, and facilitated continuum of care. We observed a mixed effect on age-appropriate immunization (e.g., DTP3 completion) and no effect on the practice of immediate breastfeeding and prevention of perinatal mortality and morbidity. The findings highlighted the effectiveness and usefulness of home-based records to improve newborn and child health outcomes. However, only a few studies were available for each outcome category, limiting the certainty of evidence provided in this review. Therefore, we recommend further studies to explore the benefits of home-based records on improving newborn and child health.

Objective This review aimed to investigate the effects of the maternal and child health (MCH) handbook and other home-based records on mothers’ non-health outcomes. Design Systematic review. Data sources PubMed, Web of Science, CINAHL, Academic Search Complete, PsycArticles, PsycINFO, SocINDEX, CENTRAL, NHS EED, HTA, DARE, Ichuushi and J-STAGE through 26 March 2022. Eligibility criteria for selecting studies Original research articles examining home-based records and mothers’ non-health outcomes published in English or Japanese across various study designs. Data extraction and synthesis Two independent reviewers extracted relevant data and assessed the risk of bias. We assessed the certainty of evidence for each study using the Grading of Recommendations Assessment, Development, and Evaluation approach. Due to the heterogeneity of the included studies, we conducted a narrative synthesis of their findings. Results Of the 4199 articles identified, we included 47 articles (20 in Japanese) in the review. Among the different types of home-based records, only the MCH handbook provided essential information about the mother–child relationship, and its use facilitated the mother–child bonding process. Mothers reported generally feeling satisfied with the use of home-based records; although their satisfaction with health services was influenced by healthcare providers’ level of commitment to using these records. While home-based records positively affected communication within the household, we observed mixed effects on communication between mothers/caregivers and healthcare providers. Barriers to effective communication included a lack of satisfactory explanations regarding the use of home-based records and personalised guidance from healthcare providers. These records were also inconsistently used across different health facilities and professionals. Conclusions The MCH handbook fostered the mother–child bond. Mothers were generally satisfied with the use of home-based records, but their engagement depended on how these records were communicated and used by healthcare providers. Additional measures are necessary to ensure the implementation and effective use of home-based records. PROSPERO registration number CRD42020166545.

For foreign-born populations, difficulty in finding health care information in their primary language is a structural barrier to accessing timely health care. While such information may be available at a national level, it may not always be relevant or appropriate to the living situations of these people. Our objective was to explore the quality of online multilingual health information environments by pilot-testing a framework for assessing such information at the prefectural level in Japan. The framework consisted of five health care domains (health system, hospitals, emergency services, medical interpreters, and health insurance). Framework scores varied considerably among prefectures; many resources were machine-translated. These scores were significantly associated with foreign population proportion and the number of hospitals in each prefecture. Our multilingual health care information environment (MHCIE) framework provides a measure of health access inclusivity, which has not been quantified before. It is adaptable to other international contexts, but further validation is required.

This study examined the associations between women’s empowerment and unmet family planning needs in five low- and middle- income countries in Southeast Asia using demographic and health survey data. The sample of ever-married women aged 15 to 49 years across five Southeast Asian countries (Cambodia [n = 10,231], Indonesia [n = 30,965], Myanmar [n = 6,644], the Philippines [n = 13,512], and Timor-Leste [n = 5,750]) were included in this study. We conducted a multiple logistic regression to analyze the associations between the four women’s empowerment indicators and unmet needs. The findings showed positive associations between women’s medium level of agreement to wife-beating, women’s decision-making, level of knowledge, and unmet needs. Both negative and positive associations were reported for labor force participation and unmet needs. Finally, improving women’s decision-making and workplace conditions and encouraging women’s labor force participation can reduce unmet needs for family planning.
