Abstract: Reproductive-age women often see increased weight gain, which carries an increased risk of long-term overweight and obesity and adverse maternal and child health outcomes. Supporting women to achieve optimal weight through lifestyle modification (diet and physical activity) is of critical importance to reduce weight gain across key reproductive life-stages (preconception, pregnancy and postpartum). This review comprehensively summarizes the current state of knowledge on the contribution of diet and physical activity to weight gain and weight gain prevention in reproductive-aged women. Suboptimal diets including a higher proportion of discretionary choices or energy intake from fats, added sugars, sweets or processed foods are associated with higher weight gain, whereas increased consumption of core foods including fruits, vegetables and whole grains and engaging in regular physical activity are associated with reduced weight gain in reproductive age women. Diet and physical activity contributing to excessive gestational weight gain are well documented. However, there is limited research assessing diet and physical activity components associated with weight gain during the preconception and postpartum period. This review highlights the need for further research to identify key dietary and physical activity components targeting the critical windows of reproductive life-stages in women to best guide interventions to prevent weight gain.

Abstract: Postpartum weight retention contributes to maternal obesity and varies by ethnicity. Despite the well-established benefits of lifestyle intervention on weight management, little is known about how to engage postpartum women effectively, especially among ethnic minority groups. This multi-methods study aimed to explore ethnic differences in women’s preferences for lifestyle intervention after childbirth. Women within five years of childbirth and living with their youngest child in Australia were recruited in an online survey (n = 504) and semi-structured interviews (n = 17). The survey and interview questions were structured based on the Template for Intervention Description and Replication (TIDieR) framework. Ethnic groups were categorized as Oceanian, Asian and Other according to the Australian Bureau of Statistics. Chi-square tests were used to compare the preferred intervention characteristics between groups. Qualitative data were thematically analysed. The survey showed that most women across all ethnic groups were interested in receiving lifestyle support in the early postpartum period (from 7 weeks to 3 months postpartum). All ethnic groups preferred a regular lifestyle intervention delivered by health professionals that promotes accountability and provides practical strategies. However, Asian women had a higher desire for infant care and a lower desire for mental health in the intervention content compared with Oceanian women. Moreover, Asian women were more likely to favour interventions that are initiated in a later postpartum period, over a shorter duration, and with less intervention frequency, compared with Oceanian women. The interviews further indicated the need for intervention adaptations in the Asian group to address the cultural relevance of food and postpartum practices. These ethnic-specific preferences should be considered in the development of culturally appropriate intervention strategies to optimize engagement in healthy lifestyles among the targeted ethnic groups.

Abstract: Insufficient physical activity (PA) and prolonged sitting time (ST) increase the risk of chronic disease and mortality. Caring for young children can potentially impact maternal PA and sedentary behaviours. The aims of this study were to explore the levels of PA and ST in women with young children (infants, toddlers and preschoolers) and sociodemographic and behavioural factors associated with these. This was a population-based cross-sectional study. Survey 5 data collected in 2009 (n = 4290) of the 1973-1978 birth cohort of the Australian Longitudinal Study on Women's Health were used. Multiple linear and logistic regression models were used to examine associations. In adjusted models, compared with women with preschoolers, women whose youngest child was an infant aged 0-6 months, aged >6-12 months or toddler had lower PA (-321.3 MET.min/week [95% confidence interval (CI) -416.2, -226.4], -147.9 MET.min/week [95% CI -237.6, -58.1] and -106.4 MET.min/week [95% CI -172.3, -40.5]). ST was higher in women whose youngest child was an infant aged 0-6 months (0.48 h/day 95% CI 0.19, 0.77) but lower with infants aged >6-12 months (-0.33 h/day 95% CI -0.60, -0.05) and toddlers (-0.40 h/day 95% CI -0.60, -0.20) than in those with preschoolers. The findings were similar in the logistic model. Sociodemographic and behavioural factors such as occupation and marital status also influenced PA and ST. Women with infants and toddlers have lower PA than women with preschoolers. Women are more likely to sit more in the first 6 months after childbirth. These findings can inform resources and intervention development to improve activity levels in women with young children through consideration of the age of the youngest child, sociodemographic and behavioural factors.

Abstract: Gestational diabetes mellitus (GDM) places a woman at high risk of developing subsequent type 2 diabetes mellitus (T2DM), particularly in the first 5 years postpartum. Engaging women in health behavior change during this period is challenging and current diabetes prevention programs were developed for middle-aged adults, all of which have limited the evidence on successful implementation for this high-risk population. In this review, we will first summarize the effects of existing diabetes prevention programs in women with a history of GDM. Second, we suggest that the programs need to be modified according to the facilitators and barriers faced by this population. Third, we propose that improving program penetration, fidelity, and participation is critical for population-level success. Finally, we outline the research priorities to improve the implementation of diabetes prevention programs for postpartum women with a history of GDM.

Abstract: A healthy postpartum lifestyle is vital for the promotion of optimal maternal health, return to pre‐pregnancy weight and prevention of postpartum weight retention, but barriers exist. We performed a systematic review that aimed to describe the barriers and facilitators to a healthy lifestyle in the first 2 years postpartum from the perspectives of women and healthcare providers. Databases were searched for eligible studies published up to 26 August 2019. Following thematic analysis, identified themes were mapped to the Theoretical Domains Framework and the Capability, Opportunity, Motivation and Behaviour model. We included 28 qualitative and quantitative studies after screening 15,643 citations and 246 full texts. We identified barriers and facilitators relating to capability (e.g., lack of knowledge regarding benefits of lifestyle behaviours limitations in healthcare providers' skills in providing lifestyle support), opportunity (e.g., social support from partners, family, friends and healthcare providers childcare needs) and motivation (e.g., identifying benefits of exercise and perception of personal health enjoyment of the activity or food). We suggest intervention components to include in lifestyle interventions for postpartum women based on the identified themes. Our findings provide evidence to inform the development of interventions to support postpartum women in adopting and maintaining a healthy lifestyle.

Abstract: Postpartum lifestyle interventions are known to be efficacious in reducing postpartum weight retention, but uptake and engagement are poor. This multi-method study explored the preferences of postpartum women for the delivery of lifestyle interventions based on the Template for Intervention Description and Replication (TIDieR) checklist. Semi-structured interviews were conducted with 21 women within 2 years of childbirth, recruited through convenience and snowball s ling throughout Australia (15 May 2020 to 20 July 2020). Transcripts were analysed thematically using an open coding approach. A cross-sectional online survey was conducted in November 2021 among postpartum women within 5 years of childbirth in Australia. Data were summarised using descriptive statistics. The survey was completed by 520 women. Both the survey and interviews revealed that women were interested in receiving lifestyle support postpartum and wanted a program delivered by health professionals. They preferred a flexible low-intensity program embedded within existing maternal and child health services that is delivered through both online and face-to-face sessions. Having a pragmatic approach that taught practical strategies and enlists the support of partners, family and peers was important to mothers. Consumer-informed postpartum lifestyle interventions promote optimal engagement and improve program reach and therefore, impact.

Abstract: Aim: This study aimed to determine the prevalence and associated factors of internet addiction among undergraduate clinical medical students of a Nigerian private university. Study Design: Cross sectional descriptive study Place and Duration of Study: College of Medicine and Allied Health Sciences, Bingham University, Jos c us, Plateau state, Nigeria, between May and July 2021. Methods: We included 383 (147 males and 236 females, age range 18 – 49 years) clinical medical students of Bingham University. Data was collected using a self-administered questionnaire which included questions about socio-demographic factors, the pattern of internet use and the standardized Internet Addiction Test questionnaire developed by Dr Kimberly S. Young in 1998. Logistic regression analysis was used to determine associations between internet addiction and various risk factors. Results: Out of 402 students who were administered questionnaires, 383 completed the questionnaires giving a response rate of 95.3%. Of these, 145 (37.9%) were mildly addicted to the internet, 30 (7.8%) were moderately addicted and 1 (0.3%) was severely addicted to the internet. The mean age of the study participants was 22.7 ± 2.7 years. Logistic regression analysis showed that age (P = .002), and having trouble sleeping (P = .002) were significantly but negatively associated with the development of internet addiction while hours spend on social media (P .001) was significantly and positively associated. Conclusions: Internet addiction is an emerging disorder in this era of almost global access to internet facilities.

Abstract: The time constraints and reprioritization of personal health associated with having children may lead women to adopt less healthy lifestyles. We assessed the patterns of change in weight and lifestyle behaviours associated with having children and whether these differ between primiparous and multiparous women. Data were from Surveys 3 and 5 of the 1973–1978 birth cohort of the Australian Longitudinal Study on Women’s Health. In women who were nulliparous at Survey 3, we assessed changes in weight, energy intake, diet (diet quality, macronutrients and micronutrients), physical activity and sitting time by parity status at Survey 5 using one-way analysis of covariance. Of 4927 eligible women, 2503 gave birth (1090 primiparous and 1413 multiparous) by Survey 5. Women who had given birth 6 years later increased weight (1.0 kg 95% CI 0.5, 1.5), energy intake (833.9 kJ/day 95% CI 706.7, 961.1) and diet quality (1.5 units 95% CI 0.8, 2.1), but decreased physical activity [–405.0 Metabolic Equivalent of Task.min/week 95% CI –464.2, –345.8] and sitting time (–1.8 h/day 95% CI –1.9, –1.6) (adjusted mean differences) relative to those who remained nulliparous. In subgroup analysis involving further stratification by parity, the increase in diet quality was only seen in women who became primiparous and the decrease in sitting time was more marked in multiparous women. Childbearing is associated with increased weight and energy intake, decreased physical activity, increased diet quality and decreased sitting time. More research targeting weight, energy intake and physical activity for improvement in women during the childbearing years is warranted.

Abstract: Postpartum weight retention (PPWR) is a strong predictor of obesity in later life with long term health consequences in women. Suboptimal lifestyle behaviours (e.g., diet and physical activity) contribute to PPWR. Postpartum lifestyle interventions are known to be efficacious in reducing PPWR however, there are challenges to their successful implementation. To inform implementation, this narrative review provides an overview of the factors that contribute to PPWR, the efficacy of existing postpartum lifestyle interventions and key determinants of effective implementation using the Consolidated Framework for Implementation Research (CFIR) across intervention characteristics, implementation process, in idual characteristics and outer and inner setting. We then suggest strategies to improve the translation of evidence into large-scale interventions that deliver on health impact in postpartum women. We have identified gaps that need to be addressed to advance postpartum lifestyle research, including the involvement of postpartum women and community members as key stakeholders for optimal reach and engagement, more complete reporting of intervention characteristics to optimize translation of evidence into practice, capacity building of health professionals and guidelines for postpartum lifestyle management.

Abstract: Reproductive and lifestyle factors influence both breast cancer risk and prognosis this might be through breast cancer subtype. Subtypes defined by immunohistochemical hormone receptor markers and gene expression signatures are used to predict prognosis of breast cancer patients based on their tumour biology. We investigated the association between established breast cancer risk factors and the 70-gene prognostication signature in breast cancer patients. Standardised questionnaires were used to obtain information on established risk factors of breast cancer from the Dutch patients of the MINDACT trial. Clinical-pathological and genomic information were obtained from the trial database. Logistic regression analyses were used to estimate the associations between lifestyle risk factors and tumour prognostic subtypes, measured by the 70-gene MammaPrint Of the 1555 breast cancer patients included, 910 had low-risk and 645 had high-risk tumours. Current body mass index (BMI), age at menarche, age at first birth, age at menopause, hormonal contraceptive use and hormone replacement therapy use were not associated with MammaPrint Using prognostic gene expression profiles, we have indications that specific reproductive factors may be associated with prognostic tumour subtypes beyond hormone receptor status.
