reduction in salt intake has been identified as one of the most cost-effective measures for improving health outcomes 1-3. Different studies have reported the benefit of salt-reduction interventions in decreasing blood pressure and cardiovascular events 4-6. Results from a meta-analysis show that modest reductions in salt intake are followed by a decrease in blood pressure levels among both hypertensive and normotensive subjects 7. Nevertheless, the evidence of the effectiveness of population-level, behavior change interventions on reducing salt intake is inconsistent, suggesting that education and awareness-raising interventions alone are not sufficient for reducing population salt intake 8. Salt substitutes, that is, salt enriched with potassium or other similar components such as magnesium or aluminum, have been reported to be effective in reducing both systolic blood pressure (SBP) and diastolic blood pressure (DBP) 9-11. Under controlled conditions, salt-substitution strategies can reduce the SBP up to 5 mm Hg and the DBP up to 1.5 mm Hg, and this effect was larger among individuals with hypertension than among normotensive subjects 12. There is limited evidence, however, from studying the population-level effect of these salt-substitution interventions. A cluster randomized trial conducted in China, evaluating the effect of a community-based sodium reduction program using a salt substitute on salt consumption and blood pressure, found reductions in urinary sodium excretion but not in blood pressure 13. Currently, an increasing number of countries have adopted national salt-reduction strategies 14. Salt-substitution initiatives could aid such strategies in settings where added salt during cooking is the main source of salt intake, particularly in low-and middle-income countries where hypertension rates are increasing at a fast rate 15. The aim of the present study was to assess the efficacy of a pragmatic intervention using a salt-substitution strategy to reduce blood pressure, as well as its impact on the incidence of hypertension, at the population level, using a stepped-wedge cluster trial in Peru. Results Population characteristics. Figure 1 shows the details of participants' enrollment, including dates, number of subjects assessed, those lost to follow-up and those analyzed for each step of the trial. A total of 2,376 (91.2%) out of 2,605 eligible subjects in the 6 villages were enrolled in the study from 2 April to 17 July, 2014: 49.6% females, mean age 43.3 ± 17.2 years. Of note, only 18.9% of the individuals had ≥12 years of education, 68.1% were in the overweight or obesity range with a body mass index (BMI) ≥25 kg m −2 and 18.3% had a diagnosis of hypertension. Table 1 shows the characteristics of the study population at baseline and a comparison between the control and the intervention periods. There were differences among villages in the distribution of age, education, wealth index, BMI, SBP, DBP and hypertension (see Supplementary Table 1).

Introduction Understanding local complexities and challenges of stroke-related caregiving are essential to develop appropriate interventions. Our study aimed to characterize the impact of post-stroke care among caregivers in a setting of transitioning economy. Materials and Methods Qualitative study based on in-depth interviews with primary caregivers of stroke survivors in Lima, Peru. Transcribed data was organized into the emotional impact of caregiving, main stress factors and coping mechanisms to deal with the caregiving role, as well as the unmet needs of caregivers. Results We interviewed twelve caregivers, mean age 52.5 years, 8/12 were females, who were either the spouse or child of the stroke survivor. Stroke patients had a median age of 70 years, range 53–85 years. All participants reported having experienced emotional stress and depressive symptoms as a result of caregiving. Although most had family support, reduced social activities and added unanticipated financial burdens increased caregiver’s stress. None of the caregivers had received training in post-stroke care tasks after the patient’s discharge and only a few had received some psychological support, yet almost all expressed the need to see a professional to improve their mental health. Keeping a positive attitude towards their relative’s physical post-stroke condition was a key coping mechanism. Conclusions In the absence of structured institutional responses, family members endure with the provision of care for stroke survivors, a task escorted by major emotional, financial, and social strains. This burden could be prevented or curtailed if caregivers were to be targeted by interventions providing psychological and financial support, together with basic training on post-stroke care.

Background: Mental, neurological, and substance (MNS) use disorders are a leading cause of disability worldwide; specifically in Peru, MNS affect 1 in 5 persons. However, the great majority of people suffering from these disorders do not access care, thereby making necessary the improvement of existing conditions including a major rearranging of current health system structures beyond care delivery strategies. This paper reviews and examines recent developments in mental health policies in Peru, presenting an overview of the initiatives currently being introduced and the main implementation challenges they face. Methods: Key documents issued by Peruvian governmental entities regarding mental health were reviewed to identify and describe the path that led to the beginning of the reform; how the ongoing reform is taking place; and, the plan and scope for scale-up. Results: Since 2004, mental health has gained importance in policies and regulations, resulting in the promotion of a mental health reform within the national healthcare system. These efforts crystallized in 2012 with the passing of Law 29889 which introduced several changes to the delivery of mental healthcare, including a restructuring of mental health service delivery to occur at the primary and secondary care levels and the introduction of supporting services to aid in patient recovery and reintegration into society. In addition, a performance-based budget was approved to guarantee the implementation of these changes. Some of the main challenges faced by this reform are related to the diversity of the implementation settings, eg, isolated rural areas, and the limitations of the existing specialized mental health institutes to substantially grow in parallel to the scaling-up efforts in order to be able to provide training and clinical support to every region of Peru. Conclusion: Although the true success of the mental healthcare reform will be determined in the coming years, thus far, Peru has achieved a number of legal, policy and fiscal milestones, thereby presenting a unique and fertile environment for the expansion of mental health services

Background Smartphone apps could constitute a cost-effective strategy to overcome health care system access barriers to mental health services for people in low- and middle-income countries. Objective The aim of this paper was to explore the patients’ perspectives of CONEMO (Emotional Control, in Spanish: Control Emocional), a technology-driven, psychoeducational, and nurse-supported intervention delivered via a smartphone app aimed at reducing depressive symptoms in people with diabetes, hypertension or both who attend public health care centers, as well as the nurses’ feedback about their role and its feasibility to be scaled up. Methods This study combines data from 2 pilot studies performed in Lima, Peru, between 2015 and 2016, to test the feasibility of CONEMO. Interviews were conducted with 29 patients with diabetes, hypertension or both with comorbid depressive symptoms who used CONEMO and 6 staff nurses who accompanied the intervention. Using a content analysis approach, interview notes from patient interviews were transferred to a digital format, coded, and categorized into 6 main domains: the perceived health benefit, usability, adherence, user satisfaction with the app, nurse’s support, and suggestions to improve the intervention. Interviews with nurses were analyzed by the same approach and categorized into 4 domains: general feedback, evaluation of training, evaluation of study activities, and feasibility of implementing this intervention within the existing structures of health system. Results Patients perceived improvement in their emotional health because of CONEMO, whereas some also reported better physical health. Many encountered some difficulties with using CONEMO, but resolved them with time and practice. However, the interactive elements of the app, such as short message service, android notifications, and pop-up messages were mostly perceived as challenging. Satisfaction with CONEMO was high, as was the self-reported adherence. Overall, patients evaluated the nurse accompaniment positively, but they suggested improvements in the technological training and an increase in the amount of contact. Nurses reported some difficulties in completing their tasks and explained that the CONEMO intervention activities competed with their everyday work routine. Conclusions Using a nurse-supported smartphone app to reduce depressive symptoms among people with chronic diseases is possible and mostly perceived beneficial by the patients, but it requires context-specific adaptations regarding the implementation of a task shifting approach within the public health care system. These results provide valuable information about user feedback for those building mobile health interventions for depression.

Background Depression is underdiagnosed and undertreated in primary health care. When associated with chronic physical disorders, it worsens outcomes. There is a clear gap in the treatment of depression in low- and middle-income countries (LMICs), where specialists and funds are scarce. Interventions supported by mobile health (mHealth) technologies may help to reduce this gap. Mobile phones are widely used in LMICs, offering potentially feasible and affordable alternatives for the management of depression among individuals with chronic disorders. Objective This study aimed to explore the potential effectiveness of an mHealth intervention to help people with depressive symptoms and comorbid hypertension or diabetes and explore the feasibility of conducting large randomized controlled trials (RCTs). Methods Emotional Control (CONEMO) is a low-intensity psychoeducational 6-week intervention delivered via mobile phones and assisted by a nurse for reducing depressive symptoms among individuals with diabetes or hypertension. CONEMO was tested in 3 pilot studies, 1 in São Paulo, Brazil, and 2 in Lima, Peru. Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9) at enrollment and at 6-week follow-up. Results The 3 pilot studies included a total of 66 people. Most participants were females aged between 41 and 60 years. There was a reduction in depressive symptoms as measured by PHQ-9 in all pilot studies. In total, 58% (38/66) of the participants reached treatment success rate (PHQ-9 <10), with 62% (13/21) from São Paulo, 62% (13/21) from the first Lima pilot, and 50% (12/24) from the second Lima pilot study. The intervention, the app, and the support offered by the nurse and nurse assistants were well received by participants in both settings. Conclusions The intervention was feasible in both settings. Clinical data suggested that CONEMO may help in decreasing participants’ depressive symptoms. The findings also indicated that it was possible to conduct RCTs in these settings.

BackgroundDoctors’ scarcity in rural areas remains a serious problem in Latin America and Peru. Few studies have explored job preferences of doctors working in underserved areas. We aimed to investigate doctors’ stated preferences for rural jobs.Methods and FindingsA labelled discrete choice experiment (DCE) was performed in Ayacucho, an underserved department of Peru. Preferences were assessed for three locations: rural community, Ayacucho city (Ayacucho’s capital) and other provincial capital city. Policy simulations were run to assess the effect of job attributes on uptake of a rural post. Multiple conditional logistic regressions were used to assess the relative importance of job attributes and of individual characteristics. A total of 102 doctors participated. They were five times more likely to choose a job post in Ayacucho city over a rural community (OR 4.97, 95%CI 1.2; 20.54). Salary increases and bonus points for specialization acted as incentives to choose a rural area, while increase in the number of years needed to get a permanent post acted as a disincentive. Being male and working in a hospital reduced considerably chances of choosing a rural job, while not living with a partner increased them. Policy simulations showed that a package of 75% salary increase, getting a permanent contract after two years in rural settings, and getting bonus points for further specialisation increased rural job uptake from 21% to 77%. A package of 50% salary increase plus bonus points for further specialisation would also increase the rural uptake from 21% to 52%.ConclusionsDoctors are five times more likely to favour a job in urban areas over rural settings. This strong preference needs to be overcome by future policies aimed at improving the scarcity of rural doctors. Some incentives, alone or combined, seem feasible and sustainable, whilst others may pose a high fiscal burden.

IMPORTANCEDepression is a leading contributor to disease burden globally. Digital mental health interventions can address the treatment gap in low-and middle-income countries, but the effectiveness in these countries is unknown.OBJECTIVE To investigate the effectiveness of a digital intervention in reducing depressive symptoms among people with diabetes and/or hypertension.
