RESUMO

Sleep difficulties and short sleep duration have been associated with hypertension. Though body mass index (BMI) may be a mediator variable, the mediation effect has not been defined. We aimed to assess the association between sleep duration and sleep difficulties with hypertension, to determine if BMI is a mediator variable, and to quantify the mediation effect. We conducted a mediation analysis and calculated prevalence ratios with 95% confidence intervals. The exposure variables were sleep duration and sleep difficulties, and the outcome was hypertension. Sleep difficulties were statistically significantly associated with a 43% higher prevalence of hypertension in multivariable analyses; results were not statistically significant for sleep duration. In these analyses, and in sex-specific subgroup analyses, we found no strong evidence that BMI mediated the association between sleep indices and risk of hypertension. Our findings suggest that BMI does not appear to mediate the association between sleep patterns and hypertension. These results highlight the need to further study the mechanisms underlying the relationship between sleep patterns and cardiovascular risk factors.

RESUMO

AIMS: The health system's response is crucial to addressing the increasing burden of diabetes, particularly that affecting low- and middle-income countries. This study aims to assess the facilitators and barriers that help or hinder access to care for people with diabetes in Peru. METHODS: We used a survey tool to design and collect qualitative and quantitative data from primary and secondary sources of information at different levels of the health system. We performed 111 interviews in Lima, the capital city of Peru, with patients with diabetes, healthcare providers and healthcare officials. We applied the six building blocks framework proposed by the World Health Organization in our analysis. RESULTS: We found low political commitment, as well as several barriers that directly affect access to medicines, regular laboratory check-ups and follow-up appointments for diabetes, especially at the primary healthcare level. Three major system-level barriers were identified: (1) the availability of information at different healthcare system levels that affects several processes in the healthcare provision; (2) insufficient financial resources; and (3) insufficient human resources trained in diabetes management. CONCLUSION: Despite an initial political commitment by the Peruvian government to improve the delivery of diabetes care, there exist several key limitations that affect access to adequate diabetes care, especially at the primary healthcare level. In a context in which various low- and middle-income countries are aiming to achieve universal health coverage, this study provides lessons for the implementation of strategies related to diabetes care delivery.
