Weight management practices, views, and experiences of adults living with poor socioeconomic circumstances and obesity: a qualitative systematic review protocol.

OBJECTIVE: The objective of this review is to synthesize the best available qualitative evidence on the weight management practices, views, and experiences of adults living with poor socioeconomic circumstances and obesity. Additionally, the review aims to deepen our understanding of the common narratives of obesity according to these people. INTRODUCTION: People living with poor socioeconomic circumstances are at increased risk of obesity, particularly in high-income countries, and their weight management practices (eg, weight-related behaviors) tend to be less healthy. Since prior research on socioeconomic inequalities in obesity is mostly from quantitative studies, the individual views and experiences related to weight management have been largely ignored. Thus, systematic qualitative evidence is needed on the weight management practices, views, and experiences of adults living with poor socioeconomic circumstances and obesity. INCLUSION CRITERIA: Qualitative studies examining adults (aged 18 to 74 years) living with poor socioeconomic circumstances and obesity, and conducted in high- and upper-middle-income countries will be considered. The phenomenon of interest is these people's weight management practices, views, and experiences. METHODS: Searches will be conducted in MEDLINE (Ovid), APA PsycINFO (Ovid), CINAHL (EBSCOhost), Scopus, Web of Science, and the Finnish health sciences database, MEDIC, restricted to the English and Finnish languages. Sources of unpublished studies and gray literature will include Google Scholar and ProQuest Dissertations and Theses. Two independent reviewers will screen the papers, assess methodological quality, and extract data following JBI's procedures. The meta-aggregative approach will be used for data synthesis. Confidence in the findings will be assessed using the ConQual approach. REVIEW REGISTRATION: PROSPERO CRD42023407938.

Wealth and Sedentary Time Are Associated With Dietary Patterns Among Preadolescents in Nairobi City, Kenya.

OBJECTIVE: The study aimed to compare dietary patterns in preadolescents in urban areas with different physical activity and socioeconomic profiles in Nairobi, Kenya. DESIGN: Cross-sectional. PARTICIPANTS: Preadolescents aged 9-14 years (n = 149) living in low- or middle-income areas in Nairobi. VARIABLES MEASURED: Sociodemographic characteristics were collected using a validated questionnaire. Weight and height were measured. Diet was assessed using a food frequency questionnaire and physical activity by accelerometer. ANALYSIS: Dietary patterns (DP) were formed through principal component analysis. Associations of age, sex, parental education, wealth, body mass index, physical activity, and sedentary time with DPs were analyzed with linear regression. RESULTS: Three DPs explained 36% of the total variance in food consumption: (1) snacks, fast food, and meat; (2) dairy products and plant protein; and (3) vegetables and refined grains. Higher wealth was associated with higher scores of the first DP (P < 0.05). CONCLUSIONS AND IMPLICATIONS: Consumption of foods often deemed unhealthy (eg, snacks and fast food) was more frequent among preadolescents whose families were wealthier. Interventions that seek ways to promote healthy lifestyles among families residing in urban areas of Kenya are warranted.

Multiple socioeconomic circumstances and trajectories of fruit and vegetable consumption: the Helsinki Health Study.

AIMS: Fruit and vegetable consumption is essential in disease prevention. Socioeconomic differences in consumption have been observed but evidence from longitudinal studies incorporating multiple socioeconomic indicators is lacking. We examined long-term fruit and vegetable consumption trajectories and multiple socioeconomic circumstances as their determinants. METHODS: We used survey data from the Helsinki Health Study (phase 1 in 2000-2002, N=8960, response rate 67%; phases 2-4 in 2007, 2012 and 2017) among initially 40- to 60-year-old employees of City of Helsinki, Finland. Fruit and vegetable consumption was measured by a food frequency questionnaire and consumption times per month were calculated. Childhood (parental education, economic difficulties), conventional (own education, occupational class, household income) and material (housing tenure, wealth, current economic difficulties) socioeconomic circumstances were included. We used group-based trajectory modelling for identifying fruit and vegetable consumption trajectories and multinomial logistic regression for examining associations between socioeconomic circumstances and the trajectories. RESULTS: Four fruit and vegetable consumption trajectories were identified: increasing higher (12%), decreasing higher (10%), stable moderate (43%) and stable low (35% of participants). Childhood, conventional and material socioeconomic circumstances were all associated with the trajectories: belonging to a lower socioeconomic group was associated with belonging to the stable low and moderate trajectories. In multivariate models, the strongest associations were found for occupational class and household wealth. CONCLUSIONS: Disadvantageous childhood and adulthood socioeconomic circumstances were associated with lower long-term fruit and vegetable consumption. Socioeconomic circumstances should be considered in attempts to promote fruit and vegetable consumption, and people with disadvantageous circumstances need to be targeted in future interventions.

Body Mass Index Trajectory-Specific Changes in Economic Circumstances: A Person-Oriented Approach Among Midlife and Ageing Finns.

Economic disadvantage is related to a higher risk of adulthood obesity, but few studies have considered whether changes in economic circumstances depend on a person's body mass index (BMI) trajectory. We identified latent BMI trajectories among midlife and ageing Finns and captured individual-level changes in economic circumstances within the BMI trajectories utilizing sequence analysis. We used the Helsinki Health Study cohort data of initially 40-60-year-old Finnish municipal employees, with four survey questionnaire phases (2000-2017). Each survey included identical questions on height and weight, and on economic circumstances incorporating household income and current economic difficulties. Based on computed BMI, we identified participants' (n = 7105; 82% women) BMI trajectories over the follow-up using group-based trajectory modeling. Four BMI trajectories were identified: stable healthy weight (34% of the participants), stable overweight (42%), overweight to class I obesity (20%), and stable class II obesity (5%). Lower household income level and having economic difficulties became more common and persistent when moving from lower- to higher-level BMI trajectories. Differences in household income widened over the follow-up between the trajectory groups, whereas economic difficulties decreased equally in all trajectory groups over time. Our study provides novel information on the dynamic interplay between long-term BMI changes and economic circumstances.

Associations of changes in diet and leisure-time physical activity with employer's direct cost of short-term sickness absence.

Several unhealthy lifestyles are associated with increased sickness absence (SA). This study examined the associations of changes in diet and leisure-time physical activity (LTPA) with employer's direct cost of subsequent short-term (<10 working days) SA. The survey data from phases 1 (2000-2002) and 2 (2007) of the Helsinki Health Study (HHS), a longitudinal cohort study of initially 40-60-year-old employees of the City of Helsinki, Finland, were linked with SA register data. Final data consisted of 4157 employees. Dietary habits were inquired with a short food frequency questionnaire. Consumption of fruits (F) and vegetables (V) was used to indicate healthiness of diet. LTPA was measured with a series of questions on the intensity and the amount of LTPA. Data on short-term SA and salaries (2008-2012) were received from the employers' registers. A two-part model was used to analyse the associations. Those who improved their F&V consumption from non-daily to daily and persevered physically active got 620 € (95% CI -1194, -47) lower cost than those remaining non-daily F&V consumers and physically inactive. When examining LTPA only, those who persevered physically active or improved from moderately active to active got 19% less cost for the employer than those remaining inactive. Dietary changes were not independently associated with the cost. Improving employees' diet and LTPA may reduce employer's direct cost of SA. Although the associations of diet with SA cost were not statistically significant, improvements in diet may contribute to the beneficial associations of LTPA and employer's cost of SA.
