Dataset Information

Job strain is prospectively associated with a lower frequency of fruit consumption in schoolteachers.

ABSTRACT:

Objective

The current study aimed to analyse the prospective association between perceived work demand and changes in eating behaviours in schoolteachers.

Design

This was a prospective cohort study with self-reported information obtained on the Demand Control Support Questionnaire and eating behaviours at baseline and after a 2-year follow-up. The analyses were performed using mixed-effects models adjusted for the main confounders.

Setting

The setting consisted of elementary and secondary schools located in a large city in southern Brazil.

Participants

The participants were 502 schoolteachers (65·9 % females, median age of 42·7 years [interquartile range 34·2, 49·4]).

Results

A total of 39·2 % of the schoolteachers were classified at baseline with job strain, 28·9 % with passive job, 12·2 % with active job and 19·7 % with low-strain job. In the fully adjusted models, compared with teachers who reported low-strain job, those with higher levels of job strain were more likely to reduce (coefficient = 0·064; 95 % CI 0·018, 0·109) and less likely to increase (coefficient = -0·066; 95 % CI -0·115, -0·016) their frequency of fruit consumption regardless of sociodemographic, lifestyle, health conditions and social support at work.

Conclusion

Job strain plays a relevant role in the frequency of fruit consumption over time in schoolteachers. The balance between demand and control at work must be considered in strategies for promoting healthy eating despite perceived social support.

Project description:BackgroundInsufficient sleep has been associated with weight gain and metabolic dysregulation, with one suggested mechanism being through reduction in diet quality. Experimental evidence supports a causal effect of sleep timings on diet but this may not be applicable to a free-living adolescent population. In this analysis we use daily measures of sleep timings and diet quality, to examine the effect of sleep duration and timing on diet quality the following day among free-living adolescents.MethodsThe ROOTS study is a prospective cohort recruited from secondary schools in Cambridgeshire and Suffolk (UK). Participants (n = 815) at mean age 15.0y (SD 0.3y) completed a diet diary and wore a combined heart rate and accelerometer device over 4 consecutive days. Sleep duration and timing (midpoint) were derived from acceleration and heart rate traces, while daily energy density and fruit and vegetable intake were calculated from dietary data. Analyses were performed at day-level (1815 person-days). Multilevel random effects models were used to test associations between sleep each night and subsequent day diet, with daily sleep and diet measures nested within individuals and schools, and adjusted for day-level and individual-level confounding variables.ResultsAdolescents slept a mean of 7.88 hrs (SD 1.10) per night, reporting a mean energy density of 2.12 kcal/g (SD 0.48) and median energy-adjusted daily fruit and vegetable intake of 137.3 g (IQR 130.4). One hour shorter sleep duration was associated with lower intake of fruit and vegetables (-6.42 g, 95%CI -1.84, -10.99) the following day. An association with higher dietary energy density (0.016 kcal/g, 95%CI 0.034, -0.002) the following day was observed but did not reach statistical significance. Sleep timing was not associated with either fruit and vegetable intake (-2.52 g/d, 95%CI -7.66, 2.62) or dietary energy density (-0.001 kcal/g, 95%CI -0.022, 0.020).ConclusionsOur observational findings from a free-living adolescent population support the experimental evidence for a causal role of sleep on diet, with shorter sleep duration at night leading to a small decrease in diet quality the following day. These findings support experimental evidence to suggest inclusion of sleep duration as one component of interventions designed to improve diet quality and weight status in adolescents.
