Ecological momentary assessment of physical activity and sedentary behaviour in shift workers and non-shift workers: Validation study.

This study examined the criterion validity of an ecological momentary assessment (EMA)-reported physical activity and sedentary time compared with accelerometry in shift workers and non-shift workers. Australian workers (n = 102) received prompts through a mobile EMA app and wore the Actigraph accelerometer on the right hip for 7-10 days. Participants received five EMA prompts per day at 3-hour intervals on their mobile phones. EMA prompts sent to shift workers (SW-T) were tailored according to their work schedule. Non-shift workers (NSW-S) received prompts at standardised times. To assess criterion validity, the association of EMA-reported activities and the Actigraph accelerometer activity counts and number of steps were used. Participants were 36 ± 11 years and 58% were female. On occasions where participants reported physical activity, acceleration counts per minute (CPM) and steps were significantly higher (ß = 1184 CPM, CI 95%: 1034, 1334; ß = 20.9 steps, CI 95%: 18.2, 23.6) than each of the other EMA activities. Acceleration counts and steps were lower when sitting was reported than when no sitting was reported by EMA. Our study showed that EMA-reported physical activity and sedentary time was significantly associated with accelerometer-derived data. Therefore, EMA can be considered to assess shift workers' movement-related behaviours with accelerometers to provide rich contextual data.

Physical activity and sedentary behaviour among south Asian immigrants in Australia.

ISSUE ADDRESSED: South Asians make up the second-largest group of immigrants in Australia and experience a higher burden of chronic diseases compared with non-immigrants. Most chronic diseases are associated with insufficient physical activity (PA) and sedentary behaviour (SB); however, studies involving PA and SB in immigrants are limited. This study aimed to explore PA and SB and associated factors among South Asian immigrants in Australia. METHODS: South Asian adult immigrants in Australia were surveyed online (from November 2020 to March 2021) about PA, SB, knowledge and barriers to PA. Logistic regressions were used to examine factors associated with insufficient PA (<150 minutes/week) and a high sitting time (>8 hours/day). RESULTS: A total of 321 participants provided complete data. Approximately 76% of participants reported insufficient PA and 27% reported high sitting time. Only 6% of participants walked or bicycled. The main reported barriers to PA were lack of time, costs, transport facilities, skills, and culturally appropriate resources. Around 52% of participants were not aware of the importance of PA. Participants with self-reported poor health and who used motorized travel were more likely to have inadequate PA. High sitting time was more common among middle-aged, overweight/obese, and middle-income participants. CONCLUSIONS: Most South Asian immigrants are insufficiently active with a lack of socio-economically appropriate PA facilities identified as a major challenge. A stronger collaboration between policymakers and community is required for sustainable solutions. SO WHAT?: Affordable and appropriate PA facilities in neighbourhoods could overcome major barriers. Also, information about PA should incorporate cultural expectations in the general recommendations to encourage participation.

Efficacy of a school-based education intervention on the consumption of fruits, vegetables and carbonated soft drinks among adolescents.

OBJECTIVES: To evaluate the efficacy of a school-based education intervention on the consumption of fruit, vegetables and carbonated soft drinks among adolescents. DESIGN: Cluster-randomised controlled trial. SETTING: Eight secondary schools from Dhaka, Bangladesh, participated in this trial and were randomly allocated to intervention (n 160) and control groups (n 160). PARTICIPANTS: A total of 320 students from 8th to 9th grades participated and completed the self-reported questionnaires at baseline, and at 8 and 12 weeks. The intervention included weekly classroom-based nutrition education sessions for students and healthy eating materials for students and parents. Repeated measures ANCOVA was used to assess the effects of the intervention. RESULTS: Daily fresh fruit intake was more frequent in the intervention (26 %) compared to the control group (3 %) at 12 weeks (p = 0·006). Participants from the intervention group also reported a significantly (P < 0·001) higher (49 %) proportion of fresh vegetable intake compared to the control group (2 %) at 12 weeks. Frequency of daily carbonated soft drinks intake decreased (25 %) in the intervention group at 12 weeks compared to baseline, while it remained unchanged in the control group; the interaction effect was observed significant (P = 0·002). CONCLUSION: Our school-based education intervention increased the daily frequency of fresh vegetables and fruit intake and decreased carbonated soft drink consumption among adolescents in the intervention group. There is a need for scaling up the intervention to engage students and empower them to develop healthy dietary habits.

The prevalence of chronic diseases in international immigrants: a systematic review and meta-analysis.

AIMS: The purpose of this study is systematically to review and synthesise available prevalence data of major chronic diseases in international immigrants. METHODS: Four electronic databases were searched to retrieve peer-reviewed original articles published in English between January 2000 and December 2020. Cross-sectional, cohort, or longitudinal studies that reported the prevalence of cardiovascular disease, any type of cancer, chronic obstructive pulmonary disease, and type 2 diabetes among immigrant adults were included. We calculated pooled prevalence using random-effects meta-analyses. RESULTS: Of 13,363 articles retrieved, 24 met the eligibility criteria. The pooled prevalence of diabetes was 9.0% (95% confidence interval (CI) 7.6-10.4) with a higher prevalence in North American countries 11.1% (95% CI 8.0-14.1) than in the other destination countries: 6.6% (95% CI 5.1-8.1) including Italy, Sweden, The Netherlands, Australia, and Israel. The pooled prevalence of cardiovascular diseases and respiratory diseases was 7.7% (95% CI 5.7-9.6) and 6.5% (95% CI 2.3-10.7), respectively. Only two articles reported the prevalence of cancers (2.7% and 3.8%). We found high heterogeneity among all studies regardless of the disease. CONCLUSIONS: The prevalence of diabetes was higher than other chronic diseases in international immigrants. There is a strong need to enhance health information systems to understand the magnitude of chronic diseases among different immigrant subgroups.

Bullying Experiences of South Asian Immigrants in Australia: a Mixed-Method Study.

Bullying is a pervasive problem faced by immigrants that negatively impacts their health and well-being. Understanding the factors that contribute to bullying and the prevalence of bullying victimisation may help to develop strategies to prevent bullying. Using a mixed-method approach, this study explored the perceptions and prevalence of bullying of South Asian immigrants living in Australia. Five focus group discussions (FGDs) were conducted to explore bullying experiences and to inform an online survey. The online survey included the California Bullying Victimisation Scale-Retrospective (CBVS-R) to measure prevalence, types, and places of bullying victimisation. Data collected from FGDs were thematically analysed while survey data were examined to identify factors associated with bullying. The main contributing factors reported by participants during FGDs were ethnic attire (clothing), religion, accent, workplace achievement, skin colour, and body shape. The online survey collected responses from 313 participants that included females (44%) and males (56%) with a mean age of 41.0 (SD ± 10.3) years. Almost 31% of participants surveyed experienced multiple bullying incidents per month with no differences observed between gender (32% in males, 31% in females). Males were mostly bullied (63%) in their workplaces while females were mostly bullied (56%) at bus or train stations. Country of birth, employment status, educational qualification, and English proficiency significantly associated with bullying experience (p < 0.001). These findings show that bullying affects male and female immigrants in different forms and settings; therefore, a large national assessment is needed to evaluate the magnitude of bullying and its consequences on immigrant health and well-being.

Associations between indicators of energy intake and expenditure with excess weight and obesity among women in sedentary and less-sedentary jobs.

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 3444 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.

Shift Work and Poor Mental Health: A Meta-Analysis of Longitudinal Studies.

Background. Shift work is characterized by employees working outside the standard hours of 7:00 am to 6:00 pm. Because shift work includes night work, the normal sleep-wake cycle (circadian rhythm) is disrupted, with potential consequences for shift workers' physical and mental health.Objectives. To assess the pooled effects of shift work on mental health and to evaluate whether these differ in men and women.Search Methods. We searched PubMed, Scopus, and Web of Science databases for peer-reviewed or government reports published up to August 2018Selection Criteria. To be included, studies had to be longitudinal or case-control studies of shift work exposure associated with adverse mental health outcomes. For subanalyses, we grouped these outcomes as anxiety symptoms, depressive symptoms, or general poor mental health symptoms.Data Collection and Analysis. We followed the Meta-Analysis of Observational Studies in Epidemiology Group guidelines. We extracted adjusted risk estimates for each study to calculate pooled effect sizes (ESs) using random effect models and metaregression analysis to explore sources of heterogeneity.Main Results. We included 7 longitudinal studies, with 28 431 unique participants. Shift work was associated with increased overall risk of adverse mental health outcomes combined (ES = 1.28; 95% confidence interval [CI] = 1.02, 1.62; I2 = 70.6%) and specifically for depressive symptoms (ES = 1.33; 95% CI = 1.02, 1.74; I2 = 31.5%). Gender differences explained more than 90% of heterogeneity, with female shift workers more likely to experience depressive symptoms than female non-shift workers (odds ratio = 1.73; 95% CI = 1.39, 2.14).Authors' Conclusions. To our knowledge, this is the first meta-analysis to investigate the pooled effects of shift work on the risk of poor mental health, including subanalyses by type of poor mental health and gender. Shift workers, particularly women, are at increased risk for poor mental health, particularly depressive symptoms.Public Health Implications. Depression accounts for 4.3% of the global burden of disease and incidence, with mental disorders worldwide predicted to cost US $16.3 million by 2030. With 1 in 5 people in the United States and Europe doing shift work, and the increased risk of poor mental health among shift workers, shift work industries are a priority context for reducing this burden. Workplace health promotion programs and policies are needed to minimize shift workers' risk of poor mental health.

A hard day's night: time use in shift workers.

BACKGROUND: Differences in how shift workers accumulate physical activity (PA) while at work and in leisure time, on days when they are working at night, during the day, or on non-work days, are largely unexplored. The aim of this study was to improve understanding of physical activity patterns in two groups of shift workers, and to measure variations according to their shift schedules. METHODS: This pragmatic pilot study was conducted in two workplaces. Employees in Workplace 1 (n = 10) were required to drive for most of their shift. Workplace 2 was a manufacturing company where most of the employees' (n = 30) occupational tasks were completed while standing. Use of time was assessed using the adult version of the Multimedia Activity Recall for Children and Adults (MARCA) administered by telephone interview. Three MARCA interviews were conducted with each participant, in order to capture a typical profile of a day-shift day, a night-shift day and a non-work day, using a two-day recall for each interview. Participants were asked to wear the activPAL3™ activity monitor, for 7 consecutive days. Paired and independent t-tests were used to compute significant differences between day-shift, night-shift and non-work days within and between workplaces. RESULTS: The total number of days quantified for the MARCA data was 192 days (64 day-shift, 60 night-shift and 68 non-work days). Workplace 2 participants reported more physical activity and less sedentary behaviour on day-shift and night shift days than on non-work days. Time spent in sedentary behaviour was similar on day-shift, night-shift and non-work days in Workplace 1. Workplace 1 participants were more sedentary (p = 0.003) and engaged in more light intensity PA (p = 0.031) on day-shift and night-shift workdays, than those from Workplace 2. Sleep times were lowest on day-shift days. CONCLUSION: As the occupational tasks for participants in Workplace 2 involved physical activities, the findings do not support the conventional view that shift workers are more sedentary than those who only work during the day. Rather occupational tasks appear to be a more important determinant of physical activity patterns both on work and non-work days than varying shift patterns.

Physical activity and sedentary behaviour in a flexible office-based workplace: Employee perceptions and priorities for change.

ISSUE ADDRESSED: Many Australian employees now regularly work from home in some capacity. This new way of working has not been widely studied in relation to the potential implications for employees' health-related behaviour or workplace health promotion. The aim of this study was to explore office-based employees' perceptions of the impact of flexible work on physical activity and sedentary behaviour; and preferences for associated interventions. METHODS: Three focus groups were conducted with office-based employees (n = 28) 6 months after the introduction of a flexible work policy. A semi-structured interview format with open-ended questions was used with summary statements to check understanding. Sessions were audiotaped, and dominant themes were identified. Findings on intervention preferences were interpreted using a social cognitive framework. An overview of results was provided to a group of managers (n = 9) for comment. RESULTS: Employees reported that physical activity was not impacted, but sedentary behaviour had increased, with flexible work. Intervention preferences focussed on occupational sedentary behaviour, self-regulation, prompts and social connections, and not the physical work environment. Managers agreed with employees' preferences and also wanted interventions to be sustainable. CONCLUSION: Self-directed interventions with social components and targeting occupational sedentary behaviour were more acceptable than physical activity interventions in this flexible workplace. SO WHAT?: Health promotion for workplaces with flexible work practices may benefit from prioritising strategies that promote self-regulation and social connections rather than being linked to the physical worksite.

The economic burden of physical inactivity: a global analysis of major non-communicable diseases.

BACKGROUND: The pandemic of physical inactivity is associated with a range of chronic diseases and early deaths. Despite the well documented disease burden, the economic burden of physical inactivity remains unquantified at the global level. A better understanding of the economic burden could help to inform resource prioritisation and motivate efforts to increase levels of physical activity worldwide. METHODS: Direct health-care costs, productivity losses, and disability-adjusted life-years (DALYs) attributable to physical inactivity were estimated with standardised methods and the best data available for 142 countries, representing 93·2% of the world's population. Direct health-care costs and DALYs were estimated for coronary heart disease, stroke, type 2 diabetes, breast cancer, and colon cancer attributable to physical inactivity. Productivity losses were estimated with a friction cost approach for physical inactivity related mortality. Analyses were based on national physical inactivity prevalence from available countries, and adjusted population attributable fractions (PAFs) associated with physical inactivity for each disease outcome and all-cause mortality. FINDINGS: Conservatively estimated, physical inactivity cost health-care systems international $ (INT$) 53·8 billion worldwide in 2013, of which $31·2 billion was paid by the public sector, $12·9 billion by the private sector, and $9·7 billion by households. In addition, physical inactivity related deaths contribute to $13·7 billion in productivity losses, and physical inactivity was responsible for 13·4 million DALYs worldwide. High-income countries bear a larger proportion of economic burden (80·8% of health-care costs and 60·4% of indirect costs), whereas low-income and middle-income countries have a larger proportion of the disease burden (75·0% of DALYs). Sensitivity analyses based on less conservative assumptions led to much higher estimates. INTERPRETATION: In addition to morbidity and premature mortality, physical inactivity is responsible for a substantial economic burden. This paper provides further justification to prioritise promotion of regular physical activity worldwide as part of a comprehensive strategy to reduce non-communicable diseases. FUNDING: None.

The economic burden of physical inactivity: a systematic review and critical appraisal.

OBJECTIVE: To summarise the literature on the economic burden of physical inactivity in populations, with emphases on appraising the methodologies and providing recommendations for future studies. DESIGN: Systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PROSPERO registration number CRD42016047705). DATA SOURCES: Electronic databases for peer-reviewed and grey literature were systematically searched, followed by reference searching and consultation with experts. ELIGIBILITY CRITERIA: Studies that examined the economic consequences of physical inactivity in a population/population-based sample, with clearly stated methodologies and at least an abstract/summary written in English. RESULTS: Of the 40 eligible studies, 27 focused on direct healthcare costs only, 13 also estimated indirect costs and one study additionally estimated household costs. For direct costs, 23 studies used a population attributable fraction (PAF) approach with estimated healthcare costs attributable to physical inactivity ranging from 0.3% to 4.6% of national healthcare expenditure; 17 studies used an econometric approach, which tended to yield higher estimates than those using a PAF approach. For indirect costs, 10 studies used a human capital approach, two used a friction cost approach and one used a value of a statistical life approach. Overall, estimates varied substantially, even within the same country, depending on analytical approaches, time frame and other methodological considerations. CONCLUSION: Estimating the economic burden of physical inactivity is an area of increasing importance that requires further development. There is a marked lack of consistency in methodological approaches and transparency of reporting. Future studies could benefit from cross-disciplinary collaborations involving economists and physical activity experts, taking a societal perspective and following best practices in conducting and reporting analysis, including accounting for potential confounding, reverse causality and comorbidity, applying discounting and sensitivity analysis, and reporting assumptions, limitations and justifications for approaches taken. We have adapted the Consolidated Health Economic Evaluation Reporting Standards checklist as a guide for future estimates of the economic burden of physical inactivity and other risk factors.

NEWS for Africa: adaptation and reliability of a built environment questionnaire for physical activity in seven African countries.

BACKGROUND: Built environment and policy interventions are effective strategies for controlling the growing worldwide deaths from physical inactivity-related non-communicable diseases. To improve built environment research and develop African specific evidence, it is important to first tailor built environment measures to African contexts and assess their psychometric properties across African countries. This study reports on the adaptation and test-retest reliability of the Neighborhood Environment Walkability Scale in seven sub-Saharan African countries (NEWS-Africa). METHODS: The original NEWS comprising 8 subscales measuring reported physical and social attributes of neighborhood environments was systematically adapted for Africa through extensive input from physical activity and public health researchers, built environment professionals, and residents in seven African countries: Cameroon, Ghana, Kenya, Mozambique, Nigeria, South Africa and Uganda. Cognitive testing of NEWS-Africa was conducted among diverse residents (N = 109, 50 youth [12 - 17 years] and 59 adults [22 - 67 years], 69 % from low socioeconomic status [SES] neighborhoods). NEWS-Africa was translated into local languages and evaluated for 2-week test-retest reliability in adult participants (N = 301; female = 50.2 %; age = 32.3 ± 12.9 years) purposively recruited from neighborhoods varying in walkability (high and low walkable) and SES (high and low income) and from villages in six of seven participating countries. RESULTS: The original 67 NEWS items was expanded to 89 scores (76 individual NEWS items and 13 computed scales). Several modifications were made to individual items, and some new items were added to capture important attributes in the African environment. A new scale on personal safety was created, and the aesthetics scale was enlarged to reflect African specific characteristics. Over 95 % of all NEWS-Africa scores (items plus computed scales) demonstrated evidence of "excellent" (ICCs > .75 %) or "good" (ICCs = 0.60 to 0.74) reliability. Seven (53.8 %) of the 13 computed NEWS scales demonstrated "excellent" agreement and the other six had "good" agreement. No items or scales demonstrated "poor" reliability (ICCs < .40). CONCLUSIONS: The systematic adaptation and initial psychometric evaluation of NEWS-Africa indicates the instrument is feasible and reliable for use with adults of diverse demographic characteristics in Africa. The measure is likely to be useful for research, surveillance of built environment conditions for planning purposes, and to evaluate physical activity and policy interventions in Africa.

The relationship between the built environment and habitual levels of physical activity in South African older adults: a pilot study.

BACKGROUND: Previous research has shown that the built environment plays a role in habitual levels of physical activity (PA), however much of this research has been conducted in adults and higher income countries. The aim of this pilot study was to examine the strength of association between the built environment and PA in South African older adults. METHODS: Participants were recruited (n = 44, mean age 65 ± 8.5 years) from two suburbs, representing either a high socioeconomic (HSA) or low socioeconomic area (LSA). Self-reported PA, and subjective assessments of neighborhood walkability (Neighborhood Environment Walkability Scale, NEWS) was measured. Participants wore Actigraph GT3x accelerometers to objectively quantify PA. RESULTS: HSA participants reported significantly more leisure-time and less transport PA. Objectively measured and self-reported MVPA was significantly higher in HSA participants. NEWS 'Land-use Mix' was negatively associated with leisure-time MVPA, (r(2) = 0.20; p < 0.02). In addition, neighborhood aesthetics was positively associated with leisure-time physical activity (r(2) = 0.33; p = 0.02). 'Safety from traffic' was inversely associated with travel-related PA (r(2) = 0.14, p = 0.01). None of the other NEWS scores were associated with PA for the total group. CONCLUSION: Leisure-time and transport-related PA was influenced by socio-economic status. Attributes of the perceived built environment associated with leisure-time and total MVPA in older South Africa adults were different in low- and high- income settings.

The association between daily steps and health, and the mediating role of body composition: a pedometer-based, cross-sectional study in an employed South African population.

BACKGROUND: Walking is recognized as an easily accessible mode of physical activity and is therefore supported as a strategy to promote health and well-being. To complement walking, pedometers have been identified as a useful tool for monitoring ambulatory physical activity, typically measuring total steps/day. There is, however, little information concerning dose-response for health outcomes in relation to intensity or duration of sustained steps. We aimed to examine this relationship, along with factors that mediate it, among employed adults. METHODS: A convenience sample, recruited from work-site health risk screening (N = 312, 37 ± 9 yrs), wore a pedometer for at least three consecutive days. Steps were classified as "aerobic" (≥100 steps/minute and ≥10 consecutive minutes) or "non-aerobic" (<100 steps/minute and/or <10 consecutive minutes). The data were sub-grouped according to intensity-based categories i.e. "no aerobic activity", "low aerobic activity" (1-20 minutes/day of aerobic activity) and "high aerobic activity" (≥21 minutes/day of aerobic activity), with the latter used as a proxy for current PA guidelines (150-minutes of moderate-intensity PA per week). Health outcomes included blood pressure, body mass index, percentage body fat, waist circumference, blood cholesterol and blood glucose. Analysis of covariance, adjusting for age, gender and total steps/day were used to compare groups according to volume and intensity-based steps categories. A further analysis compared the mediation effect of body fat estimates (percentage body fat, body mass index and waist circumference) on the association between steps and health outcomes, independently. RESULTS: Average steps/day were 6,574 ± 3,541; total steps/day were inversely associated with most health outcomes in the expected direction (p < 0.05). The "no aerobic activity" group was significantly different from the "low aerobic activity" and "high aerobic activity" in percentage body fat and diastolic blood pressure only (P < 0.05). Percentage body fat emerged as the strongest mediator of the relationship between steps and outcomes, while body mass index showed the least mediation effect. CONCLUSION: The study provides a presentation of cross-sectional pedometer data that relate to a combination of intensity and volume-based steps/day and its relationship to current guidelines. The integration of volume, intensity and duration of ambulatory physical activity in pedometer-based messages is of emerging relevance.

Nurses' lifestyle behaviours, health priorities and barriers to living a healthy lifestyle: a qualitative descriptive study.

BACKGROUND: Nurses have an increased risk for non-communicable diseases (NCDs), along with a high prevalence of obesity, poor eating habits and insufficient physical activity. The aim of this study was to determine the health concerns, health priorities and barriers to living a healthy lifestyle among nurses and hospital management staff from public hospitals in the Western Cape Metropole, South Africa. METHODS: Participants were purposively sampled (n = 103), and included management personnel (n = 9), night shift (n = 57) and day-shift nurses (n = 36). Twelve focus groups (FGDs) were conducted with nursing staff to obtain insight into nurses' health concerns, lifestyle behaviours and worksite health promotion programmes (WHPPs). Seven key informant interviews (KII) were conducted with management personnel, to gain their perspective on health promotion in the worksite. Thematic analysis was used to analyse the data with the assistance of Atlas.ti Qualitative Data Analysis Software. RESULTS: Night shift nurses frequently identified weight gain and living with NCDs such as hypertension as their main health concerns. Being overweight was perceived to have a negative impact on work performance. All nurses identified backache and exposure to tuberculosis (TB) as occupation-related health concerns, and both management and nurses frequently reported a stressful working environment. Nurses frequently mentioned lack of time to prepare healthy meals due to long working hours and being overtired from work. The hospital environment was perceived to have a negative influence on the nurses' lifestyle behaviours, including food service that offered predominantly unhealthy foods. The most commonly delivered WHPPs included independent counselling services, an online employee wellness programme offered by the Department of Health and wellness days in which clinical measures, such as blood glucose were measured. Nurses identified a preference for WHPPs that provided access to fitness facilities or support groups. CONCLUSIONS: Public hospitals are a stressful work environment and shift work places an additional strain on nurses. The risk of NCDs and exposure to infectious disease remains a concern in this working population. Our findings highlight the need for WHPPs that support nurses in managing stress and transforming the work environment to facilitate healthy lifestyles.

Physical activity interventions among youth living in rural and remote areas: A systematic review.

OBJECTIVES: Physical activity (PA) interventions have potential to improve health and social outcomes among youth. The aim of this study was to collate the evidence on the effectiveness of PA and sports-based interventions among youth living in rural and remote areas. METHODS: We searched five databases and grey literature (HealthInfoNet). Search terms included PA, rural status, adolescents, and outcome measures. Studies were included if published in English, recruited 10- to 18-year olds, and were based in rural or remote communities (Modified Monash Model [MMM] area classification range of MMM 3-7). Quasi-experimental and pre-experimental and post-experimental PA interventions were included. Two authors evaluated the articles independently following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, and relevant data were extracted. International Prospective Register of Systematic Reviews (PROSPERO) (CRD42020199001). RESULTS: Of the 11802 studies identified, 6 were included in the review. Most studies were excluded for not meeting MMM 3-7 criteria. Four of the included studies had sports-related interventions, and 2 had walking-based interventions. Outcomes included self-efficacy, mental health, and academic performance. One study reported a positive effect of PA on self-efficacy (ß = 0.26, p=0.018, odds ratio = 1.43 [95% confidence interval: 1.07-1.92]). CONCLUSION: Few community-based PA interventions have been evaluated in rural areas. There is a need for future evaluations in rural areas and include PA as an outcome measure. IMPLICATIONS FOR PUBLIC HEALTH: The findings highlight the need for measurement of PA outcomes in PA interventions in rural and remote areas. The findings also highlight the need for research to utilise a standardised measure of rurality.

Clustering of risk factors for non-communicable disease and healthcare expenditure in employees with private health insurance presenting for health risk appraisal: a cross-sectional study.

BACKGROUND: The global increase in the prevalence of NCD's is accompanied by an increase in risk factors for these diseases such as insufficient physical activity and poor nutritional habits. The main aims of this research study were to determine the extent to which insufficient physical activity (PA) clustered with other risk factors for non-communicable disease (NCD) in employed persons undergoing health risk assessment, and whether these risk factors were associated with higher healthcare costs. METHODS: Employees from 68 companies voluntarily participated in worksite wellness days, that included an assessment of self-reported health behaviors and clinical measures, such as: blood pressure (BP), Body Mass Index (BMI), as well as total cholesterol concentrations from capillary blood samples. A risk-related age, 'Vitality Risk Age' was calculated for each participant using an algorithm that incorporated multiplicative pooled relative risks for all cause mortality associated with smoking, PA, fruit and vegetable intake, BMI, BP and cholesterol concentration. Healthcare cost data were obtained for employees (n = 2 789). RESULTS: Participants were 36±10 years old and the most prevalent risk factors were insufficient PA (67%) and BMI ≥ 25 (62%). Employees who were insufficiently active also had a greater number of other NCD risk factors, compared to those meeting PA recommendations (chi2 = 43.55; p < 0.0001). Moreover, employees meeting PA guidelines had significantly fewer visits to their family doctor (GP) (2.5 versus 3.11; p < 0.001) than those who were insufficiently PA, which was associated with an average cost saving of ZAR100 per year (p < 0.01). Furthermore, for every additional year that the 'Vitality Risk Age' was greater than chronological age, there was a 3% increased likelihood of at least one additional visit to the doctor (OR = 1.03; 95% CI = 1.01 - 1.05). CONCLUSION: Physical inactivity was associated with clustering of risk factors for NCD in SA employees. Employees with lower BMI, better self-reported health status and readiness to change were more likely to meet the PA guidelines. These employees might therefore benefit from physical activity intervention programs that could result in improved risk profile and reduced healthcare expenditure.

The Feasibility of a Text-Messaging Intervention Promoting Physical Activity in Shift Workers: A Process Evaluation.

Workplace health promotion programs (WHPPs) can improve shift workers' physical activity. The purpose of this paper is to present the process evaluation of a text messaging health promotion intervention for mining shift workers during a 24-day shift cycle. Data collected from intervention participants with a logbook (n = 25) throughout the intervention, exit interviews (n = 7) and online surveys (n = 17) examined the WHPP using the RE-AIM (Reach, Efficacy, Adoption, Implementation and Maintenance) framework. The program reached 66% of workers across three departments, with 15% of participants dropping out. The program showed the potential to be adopted if the recruitment strategies are improved to reach more employees, especially when involving work managers for recruitment. A few changes were made to the program, and participant adherence was high. Facilitators to adopt and implement the health promotion program included the use of text messaging to improve physical activity, feedback on behaviour, and providing incentives. Work-related fatigue was reported as a barrier to implementing the program. Participants reported that they would recommend the program to other workers and use the Mi fitness band to continue monitoring and improving their health behaviour. This study showed that shift workers were optimistic about health promotion. Allowing for long-term evaluation and involving the company management to determine scale-up should be considered for future programs.
