The aim of this study was to compare the associations between indicators of energy intake and expenditure with excess weight and obesity in women who work full-time in sedentary and less sedentary jobs.
Data were from 3,444 participants the Australian Longitudinal Study on Women’s Health, who reported their weight, dietary intake, physical activity and occupation in 2009 (baseline), and weight in 2012 (follow-up). Participants were categorised as being in a ‘less sedentary’ or ‘sedentary’ job, based on occupational activity patterns. Odds of excess weight (BMI≥25) at baseline and of being obese (BMI≥30) at follow-up, by indicators of energy intake and expenditure, were compared in the two occupational groups.
In multivariate analyses, high non-work sitting time and saturated fat intake were associated with increased odds of obesity at 3-year follow-up in both occupational groups. In the sedentary job group, high physical activity (in leisure and transport) was associated with a 51% reduction in odds of obesity (OR 0.49, 95%CI 0.25-0.97). In the less-sedentary job group, energy intake and high soft drink consumption were associated with markedly increased odds of obesity (OR 1.67 95%CI 1.07-2.61; OR 2.08 95%CI1.42-3.05, respectively).
In this cohort of young Australian women, sedentariness at work did not markedly affect the prevalence of excess weight or obesity. Indicators of high energy intake and low energy expenditure were associated with increased odds of both excess weight and obesity, regardless of sedentariness of occupational group.

The positive effects of dietary fibre on gut barrier function and inflammation have not been completely elucidated. Mice studies show gut barrier disruption and diet-induced insulin resistance can be alleviated by cytokine interleukin-22 (IL-22). However, little is known about IL-22 in humans and its association with gut-beneficial nutrients like fibre. We investigated whether fibre intake was associated with circulating levels of IL-22 in 48 participants with metabolic syndrome (MetS). Bivariate analysis was used to explore associations between circulating IL-22, fibre intake, MetS factors, body composition, and cardiorespiratory fitness (peak oxygen uptake, V ˙ O2peak). Hierarchical multiple regression (HMR) was used to test the independent association of fibre intake with circulating IL-22, adjusting for variables correlated with IL-22. Circulating IL-22 was positively associated with fibre intake (rs = 0.393, p < 0.006). The HMR-adjusted model explained 40% of circulating IL-22 variability, and fibre intake significantly improved the prediction model by 8.4% (p < 0.022). Participants with fibre intake above median intake of 21.5 g/day had a significantly higher circulating IL-22 than the lower intake group (308.3 ± 454.4 vs. 69.0 ± 106.4 pg/mL, p < 0.019). Fibre intake is independently associated with increased circulating IL-22 in individuals with MetS. Findings warrant further investigations to evaluate whether changes in dietary fibre intake alter circulating IL-22, and its effects on health outcomes.

Physical activity (PA) is an independent predictor of mortality and frailty in middle-aged women, but fatigue remains a major barrier in this group. While caffeine intake has been associated with reduced exertion and perceived fatigue, it is not well understood whether consumption of naturally caffeinated drinks is associated with physical activity. The aim of this study was to determine whether habitual consumption of coffee and tea is associated with participation in physical activity. Women (n = 7580) from the Australian Longitudinal Study on Women's Health were included in this investigation. Participants reported average tea and coffee intake over the last 12 months and usual PA. Logistic regression models were adjusted for relevant health and lifestyle confounders, and Sobel test was used for mediation analysis. Participants who consumed 1⁻2 cups of coffee/day were 17% more likely to meet the recommended 500 metabolic equivalent (MET).min/week than women who had 3 cups/day of tea were 13⁻26% more likely to meet 500 MET.min/week than those who had 1 cup of tea/day are more likely to meet the moderate-to-vigorous PA guidelines than those who drink

© 2017 Society for Nutrition Education and Behavior Objective: to use the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework to evaluate and understand key implementation and context factors of a diet and physical activity (PA) workplace intervention for nurses. Methods: a 3-month pilot intervention was developed to promote diet and PA behavior through self-monitoring, goal setting, and social support using pedometers, a smartphone app, and a dedicated Facebook group. Measures included diet quality, daily PA, adoption, and implementation (including qualitative data). Maintenance was assessed at 6-month follow-up. Results: Forty-seven nurses participated in the study. At 3 months, fruit and vegetable intake significantly increased (P =.04) whereas PA significantly decreased (P =.01). The intervention was partially adopted as planned, with low reach and efficacy. Participants reported that changing 2 behaviors at the same time was difficult, with the majority feeling it was easier to change diet than to become more physically active. Conclusions and Implications: the ability to change diet and PA behaviors at the same time was challenging in nurses. Future studies examining whether similar occupational groups with high stress, fatigue, and lack of time face the same challenges would contribute to understanding these results.

© 2018 World Obesity Federation the purpose of this review and meta-analysis was to evaluate overweight and obesity as risk factors for urinary incontinence in young to mid-aged women. Understanding these relationships during this life stage is important as early onset increases the risk for developing severe and persistent incontinence. A systematic search resulted in 497 citations, 14 of which were retained for review. Data were analysed by overweight and obesity and by subtype of urinary incontinence – stress, urge, mixed and severe. When compared with ‘normal’ body mass index, overweight was associated with a one-third increase in risk of urinary incontinence (relative risk = 1.35, 95% confidence interval = 1.20–1.53), while the risk was doubled in women with obesity (relative risk = 1.95, 95% confidence interval = 1.58–2.42). When estimates were pooled according to urinary incontinence subtype, there was no statistical difference in risk. Overweight and obesity are strong predictors of urinary incontinence, with a significantly greater risk observed for obesity. Clinical advice to young women at risk of, or presenting with, obesity should not be limited to metabolic health only but should emphasize the role of excess weight on pelvic floor weakening and subsequent risk of incontinence.

Objective. To systematically review the effectiveness of intervention studies promoting diet and physical activity (PA) in nurses. Data Source. English language manuscripts published between 1970 and 2014 in PubMed, Scopus, CINAHL, and EMBASE, as well as those accessed with the PICO tool, were reviewed. Study Inclusion and Exclusion Criteria. Inclusion criteria comprised (1) nurses/student nurses working in a health care setting and (2) interventions where PA and/or diet behaviors were the primary outcome. Exclusion criteria were (1) non–peer-reviewed articles or conference abstracts and (2) interventions focused on treatment of chronic conditions or lifestyle factors other than PA or diet in nurses. Data Extraction. Seventy-one full texts were retrieved and assessed for inclusion by two reviewers. Data were extracted by one reviewer and checked for accuracy by a second reviewer. Data Synthesis. Extracted data were synthesized in a tabular format and narrative summary. Results. Nine (n = 737 nurses) studies met the inclusion criteria. Quality of the studies was low to moderate. Four studies reported an increase in self-reported PA through structured exercise and goal setting. Dietary outcomes were generally positive, but were only measured in three studies with some limitations in the assessment methods. Two studies reported improved body composition without significant changes in diet or PA. Conclusions. Outcomes of interventions to change nurses’ PA and diet behavior are promising, but inconsistent. Additional and higher quality interventions that include objective and validated outcome measures and appropriate process evaluation are required.
