Mexico has a concentrated HIV epidemic, with male sex workers constituting a key affected population. We estimated annual HIV cumulative incidence among male sex workers’ partners, and then compared incidence under three hypothetical intervention scenarios: improving condom use; and scaling up HIV treatment as prevention, considering current viral suppression rates (CVS, 60.7 %) or full viral suppression among those treated (FVS, 100 %). Clinical and behavioral data to inform model parameterization were derived from a sample (n = 79) of male sex workers recruited from street locations and Clínica Condesa, an HIV clinic in Mexico City. We estimated annual HIV incidence among male sex workers’ partners to be 8.0 % (95 % CI: 7.3–8.7). Simulation models demonstrated that increasing condom use by 10 %, and scaling up HIV treatment initiation by 50 % (from baseline values) would decrease the male sex workers-attributable annual incidence to 5.2, 4.4 % (CVS) and 3.2 % (FVS), respectively. Scaling up the number of male sex workers on ART and implementing interventions to ensure adherence is urgently required to decrease HIV incidence among male sex workers’ partners in Mexico City. © 2014, Springer Science+Business Media New York.

Background: Effective access measures are intended to reflect progress toward universal health coverage. This study proposes an operative approach to measuring effective access: in addition to the lack of financial protection, the willingness to make out-of-pocket payments for health care signifies a lack of effective access to pre-paid services. Methods. Using data from a nationally representative health survey in Mexico, effective access at the individual level was determined by combining financial protection and effective utilization of pre-paid health services as required. The measure of effective access was estimated overall, by sex, by socioeconomic level, and by federal state for 2006 and 2012. Results: In 2012, 48.49% of the Mexican population had no effective access to health services. Though this represents an improvement since 2006, when 65.9% lacked effective access, it still constitutes a major challenge for the health system. Effective access in Mexico presents significant heterogeneity in terms of federal state and socioeconomic level. Conclusions: Measuring effective access will contribute to better target strategies toward universal health coverage. The analysis presented here highlights a need to improve quality, availability, and opportuneness (location and time) of health services provision in Mexico. © 2014 Gutiérrez et al.; licensee BioMed Central Ltd.

In 2010, the Mexican government implemented a multi-sector agreement to prevent obesity. In response, the Ministries of Health and Education launched a national school-based policy to increase physical activity, improve nutrition literacy, and regulate school food offerings through nutritional guidelines. We studied the Guidelines' negotiation and regulatory review process, including government collaboration and industry response. Within the government, conflicting positions were evident: the Ministries of Health and Education supported the Guidelines as an effective obesity-prevention strategy, while the Ministries of Economics and Agriculture viewed them as potentially damaging to the economy and job generation. The food and beverage industries opposed and delayed the process, arguing that regulation was costly, with negative impacts on jobs and revenues. The proposed Guidelines suffered revisions that lowered standards initially put forward. We documented the need to improve cross-agency cooperation to achieve effective policymaking. The 'siloed' government working style presented a barrier to efforts to resist industry's influence and strong lobbying. Our results are relevant to public health policymakers working in childhood obesity prevention. © 2015 Macmillan Publishers Ltd. Source

Global HIV control funding falls short of need. To maximize health outcomes, it is critical that national governments sustain reasonable commitments, and that international donor assistance be distributed according to country needs and funding gaps. We develop a country classification framework in terms of actual versus expected national domestic funding, considering resource needs and donor financing. With UNAIDS and World Bank data, we examine domestic and donor HIV program funding in relation to need in 84 low- and middle-income countries. We estimate expected domestic contributions per person living with HIV (PLWH) as a function of per capita income, relative size of the health sector, and per capita foreign debt service. Countries are categorized according to levels of actual versus expected domestic contributions, and resource gap. Compared to national resource needs (UNAIDS Investment Framework), we identify imbalances among countries in actual versus expected domestic and donor contributions: 17 countries, with relatively high HIV prevalence and GNI per capita, have domestic funding below expected (median per PLWH $143 and $376, respectively), yet total available funding including from donors would exceed the need ($368 and $305, respectively) if domestic contribution equaled expected. Conversely, 27 countries have actual domestic funding above the expected (medians $294 and $149) but total (domestic+donor) funding does not meet estimated need ($685 and $1,173). Across the 84 countries, in 2009, estimated resource need totaled $10.3 billion, actual domestic contributions $5.1 billion and actual donor contributions $3.7 billion. If domestic contributions would increase to the expected level in countries where the actual was below expected, total domestic contributions would increase to $7.4 billion, turning a funding gap of $1.5 billion into a surplus of $0.8 billion. Even with imperfect funding and resource-need data, the proposed country classification could help improve coherence and efficiency in domestic and international allocations. © 2013 Galárraga et al.

As antiretroviral treatment (ART) for HIVAIDS is scaled up globally, information on per-person costs is critical to improve efficiency in service delivery and to maximize coverage and health impact. The objective of this study was to review studies on unit costs for delivery of adult and paediatric ART per patient-year, and prevention of mother-to-child transmission (PMTCT) interventions per mother-infant pair screened or treated, in low- and middle-income countries. A systematic review was conducted of English, French and Spanish publications from 2001 to 2009, reporting empirical costing that accounted for at least antiretroviral (ARV) medicines, laboratory testing and personnel. Expenditures were analysed by country-income level and cost component. All costs were standardized to $US, year 2009 values. Several sensitivity analyses were conducted.Analyses covered 29 eligible, comprehensive, costing studies. In the base case, in low-income countries (LIC), median ART cost per patient-year was $US792 (mean: 839, range: 6821089); for lower-middle-income countries (LMIC), the median was $US932 (mean: 1246, range: 1563904); and, for upper-middle-income countries (UMIC), the median was $US1454 (mean: 2783, range: 12305667). ARV drugs were the largest component of overall ART costs in all settings (64, 50 and 47 in LIC, LMIC and UMIC, respectively). Of 26 ART studies, 14 reported the drug regimes used, and only one study explicitly reported second-line treatment costs. The second cost driver was laboratory cost in LIC and LMIC (14 and 20), and personnel costs in UMIC (26). Two ART studies specified the types of laboratory tests costed, and three studies specifically included above facility-level personnel costs. Three studies reported detailed PMTCT costs, and three studies reported on paediatric ART.There is a paucity of data on the full unit costs for delivery of ART and PMTCT, particularly for LIC and middle-income countries. Heterogeneity in activities costed, and insufficient detail regarding components included in the costing, hampers standardization of unit cost measures. Evaluation of programme-level unit costs would benefit from international guidance on standardized costing methods, and expenditure categories and definitions. Future work should help elucidate the sources of the large variations in delivery unit costs across settings with similar income and epidemiological characteristics. © 2011 Adis Data Information BV.
