  • *Percentages were obtained in the analysis taking into account the sampling design

  • †The Gini coefficient is an international parameter used to measure the inequality in income distribution among countries. A Gini coefficient >50th centile means high income inequality.

  • **Numbers may not add to totals due to weight and rounding, beside missing information for hypertension (n=17), Gini coefficient (n=25), number of inhabitants (n=125), and on-site staff canteen (n=220).
