Shift work affects many areas of workers' lives, negatively impacting on eating and lifestyle behaviours and psychosocial health. This study augments the current literature as it highlights the role internal motivation plays in workers' lifestyle choices. The research should help inform the development of public health strategies to minimize the impact of shift work, such as specialist behavioural change interventions specific to this group.

Investing in employee health is beneficial, particularly among shift workers, who are at an increased health risk. Adopting organizational policies and environmental changes as a core strategy for workplace health promotion may create an environment that makes healthier choices more accessible to all employees.

Within the home environment, parents influence their children’s dietary intakes through their parenting and dietary practices, and the foods they make available/accessible. The aim of this cross-sectional study was to examine the associations between home environmental characteristics and children’s dietary intakes. Three hundred and thirty-two children aged three–five years and their parents participated in the study. Home environmental characteristics, including parental control feeding practices, were explored using validated and standardized questionnaires such as the Child Feeding Questionnaire (CFQ), the Physical and Nutritional Home Environment Inventory (PNHEI) and the Healthy Home Survey (HHS). Parent and child food consumption was also measured. Pressure to eat from parents was associated with lower fruit intake in children (OR 0.67, 95% CI 0.47–0.96, p = 0.032). Greater variety of fruit available in the home increased the likelihood of fruit consumption in children (OR 1.35 95% CI 1.09–1.68, p = 0.005). Watching television for ≥1 h per day was associated with a decreased probability of children eating vegetables daily (OR 0.38, 95% CI 0.20–0.72, p = 0.003) and doubled their likelihood of consuming confectionary/sugar-sweetened beverages more than once weekly (OR 2.15, 95% CI 1.06–4.38, p = 0.034). Children whose parents had lower vegetable consumption were 59% less likely to eat vegetables daily. This study demonstrates that modifiable home environmental characteristics are significantly associated with children’s dietary intakes.

In Ireland, television (TV) screen time is a highly prevalent sedentary behavior among children aged less than five years. Little is known about the influence of parental rules and policies or screen time availability and accessibility within the home on children’s TV screen time behaviors. This cross-sectional study aimed to examine the extent to which parents’ sociodemographic and sedentary behaviors are associated with children’s TV screen time; and to determine the associations between parents’ rules and practices, home physical environment and children’s daily TV viewing. Three hundred and thirty-two children aged 3–5 years and their parents participated in the study. Children’s TV screen time and home environmental characteristics (parents’ rules and practices and the physical environment) were assessed using questions from standardized and validated questionnaires. The data were analyzed using binary logistic regression. Within the different sedentary behaviors evaluated, parents’ TV viewing was positively associated with children’s TV screen time (OR 1.65, 95%CI 1.09–2.50, p = 0.018). Leaving the TV on, whether or not it was being watched, was associated with a 38% increased probability of children watching ≥ 1 h TV daily. Children whose parents restricted their outdoor activity were more likely to watch ≥ 1 h TV daily (OR 2.01, 95%CI 1.04–3.88, p = 0.036). Findings from the study demonstrated that parents’ own screen time behaviors, leaving the TV on whether it was being watched or not and restricting outdoor play were associated with higher children’s TV viewing in the home environment. This knowledge is essential to inform future interventions aimed to address the increase in screen time among young children.
