ABSTRACT

Purpose A staff canteen in the workplace can offer a healthier diet, which may lower blood pressure. This study aimed to evaluate whether the presence of staff canteen in the workplace is associated with consumption of healthy food and lower systolic and diastolic blood pressure. Design/methodology/approach A cross-sectional study was conducted, randomly selecting workers through a multistage sampling, stratified by company size in Brazil. Demographic, socioeconomic, and lifestyle characteristics were evaluated, and weight, height, and blood pressure were measured. Statistical analysis used Generalized Linear Models, controlling for design effect and confounding factors, to assess the association between blood pressure and staff canteen and the intake of food items. Findings 4.818 Workers, aged 35.4 ±10.7 years, 76.5% men, with 8.7 ±4.1 years of formal education were enrolled. Prevalence of hypertension was 24.7% (P value <0.001) among workers from industries with staff canteen versus 30.6% among those with no staff canteen. Workers of industries with staff canteen consumed higher proportion of fruits, green leafy vegetables, and milk than workers of industries without canteen, and had lower systolic and diastolic blood pressure, independently of the frequency of intake. Practical implications Workers of industries with staff canteen consumed a healthier diet, and had lower systolic and diastolic blood pressure, and lower prevalence of hypertension than workers from workplaces without staff canteen. Originality/value This study was the first carried out among workers of industries reporting that the presence of a staff canteen in the workplace is associated with lower systolic and diastolic blood pressure and prevalence of hypertension.

DISCUSSION

This study was the first study conducted in a representative sample of workers from Brazilian industries investigating risks for high blood pressure. It showed that the presence of a staff canteen in the workplace was associated with higher intake of milk and vegetables servings and lower systolic and diastolic blood pressure. Moreover, there were interactions of systolic and diastolic blood pressure with having a staff canteen in the workplace and intake of different types of meat, milk, fruits, vegetables, and green leafy vegetables. Although a staff canteen in the workplace provides food availability, workers had lower systolic and diastolic blood pressure, even with high intake of red and sausage meats, compared with those who did work in non-canteen industries. Workers are a distinct group of the general population, since to be admitted to a job and in order to maintain it, it is necessary to be healthy. Despite of this, Asay et al. (2016) reported high prevalence of risk factors for cardiovascular disease in workers, and the presence of hypertension may result in absenteeism at high costs.

The results of this large cross-sectional study confirms previous findings of an inverse association between hypertension and total dairy (Soedamah-Muthu et al., 2012), fruits and vegetables (Thorsen et al., 2010), and a direct association with meat intake (Borgi et al., 2015; Lajous et al., 2014). The presence of canteen at the workplace was associated with the type of food intake as well. This study did not investigate the association between a staff canteen and blood pressure. A government of Australia report (Health.vic.gov.au, 2017) showed that the use of catering services has been associated with healthy eating habits and employees who eat lunch at the worksite canteens tend to make similar food choices to the nutritional recommendations. The existence of staff canteen at workplace varies across countries (Kjollesdal et al., 2010). In Brazil, approximately 70% of workers have a canteen in the workplace.
