Aim: The study evaluated the impact of lifestyle intervention on body weight, metabolic syndrome parameters, nutrition and physical activity in home-care providers (HCPs).
Methods: Of 551 screened employees of a nursing agency, 173 were eligible to participate and were assigned to either the intervention (n=129) or the control (n=44) group. Participants in the intervention group followed an educational programme that encouraged physical activity and healthy nutrition, and were equipped with bicycles free of charge. Anthropometric, biological and lifestyle parameters were assessed at baseline, and after 6 and 12 months.
Results: Body weight, waist circumference and systolic blood pressure significantly decreased at 12 months in both study groups. Incidence of the metabolic syndrome in the intervention group at 12 months was reduced by 50% (from 17 to 9.2%; P=0.04). There were also decreases in LDL cholesterol (-0.36 mmol/L; P<0.01), total cholesterol/HDL cholesterol ratio (-0.57; P<0.01) and fasting glucose (-0.4 mmol/L; P<0.05), and an increase in HDL cholesterol (+0.22 mmol/L; P<0.01) in the intervention group. At 12 months, a decrease in daily caloric intake (-391 kcal/day; P<0.001) and an increase in the percentage of participants engaging in physical activity (+3.4%; P<0.05) were also observed in the intervention group.
Conclusion: Lifestyle changes among HCPs are possible with relatively modest behavioural education and within a short period of time. Educational strategies and workshops are effective, efficient and easy to perform, and should be encouraged in HCPs to promote the implementation of lifestyle modifications in their patients.
