Socioeconomic inequalities in the use of medical consultation services in Peru, 2019.

BACKGROUND: Socioeconomic inequalities in the population influence access to health services and constitute a challenge for health systems, especially in low- and middle-income countries. In Peru, an increase in the use of medical services has been estimated; however, the study of inequalities in the use of medical services is limited. Therefore, the objective of this research was to analyze and decompose socioeconomic inequalities in the use of medical consultation services in Peru. METHODS: A cross-sectional analytical study was conducted using data from the National Household Survey 2019. The outcome variable was the use of a consultation attended by a physician in the last 4 weeks in persons who presented symptom or discomfort, illness, relapse of chronic disease and/or accident. Concentration curves and Erreygers concentration indices were used to determine socioeconomic inequalities, and a generalized linear regression model was used for the decomposition analysis of inequalities. RESULTS: A total of 52,715 persons were included in the study. The frequency of medical consultation was 25.4% (95% confidence interval: 24.8 - 26.1%). In the inequality analysis, it was found that the use of medical consultations was concentrated among the wealthiest individuals. The main contributing factors were having another type of health insurance (social health insurance [EsSalud], private health insurance, health provider, the Armed Forces, and the Police), residing in an urban area, belonging to the richest wealth quintile, having a chronic disease, and residing in the highlands of Peru. CONCLUSIONS: Based on our findings, government institutions seeking to achieve equitable access to health services should consider the main factors contributing to this inequality in the formulation of strategies to lessen the negative impact of inadequate disease control in the population.

Measuring Socioeconomic Inequalities in HIV Testing During Antenatal Care: A Peruvian National Survey.

Although several Latin American countries have 70% antenatal care coverage, the proportion of human immunodeficiency virus (HIV) testing of Peruvian pregnant women and the socioeconomic inequalities of this preventive measure are unknown. This study aimed to determine socioeconomic inequalities and quantify the contribution of contextual and compositional factors on HIV testing during prenatal care in Peru. A cross-sectional study of the 2021 Demographic and Family Health Survey data was conducted. The outcome variable was HIV testing of pregnant women during prenatal care. An analysis of inequalities was performed including the determination of concentration curves and a decomposition analysis of concentration indices. Of a total of 17521 women aged 15 to 49 years, 91.4% had been tested for HIV during prenatal care. The concentration curves showed that prenatal HIV testing was concentrated among richer women, while the decomposition analysis determined that the main contributors to inequality were having a higher education, residing in an urban area, and in the highlands, belonging to the wealthy quintile, and being exposed to television and newspapers. Strategies focused on improving access, promotion and restructuring of prevention of mother-to-child transmission measures should be prioritized.

Impact of health insurance on the use of oral health services in the Peruvian population 2015-2019.

BACKGROUND: The high treatment cost of oral diseases is a barrier for accessing oral health services (OHS), particularly in low-income countries. Therefore, this study aimed to evaluate the impact of health insurance on the use of OHS in the Peruvian population from 2015 to 2019. METHODS: We conducted a prospective, longitudinal study of secondary data using the National Household Survey (ENAHO) 2015-2019 panel databases, which collected information from the same participants during each of the five years. The dependent variable was the use of OHS in the three months prior to the survey (yes/no). The independent variable was health insurance affiliation (four years or less/all five years). Both were measured by survey questions. Generalized estimating equation (GEE) Poisson regression models with robust standard errors were used to estimate the relative risk (RR) associated with use of OHS. RESULTS: We included 4064 individuals distributed in 1847 households, who responded to the survey during each of the five years. The adjusted GEE model showed that those who had health insurance during all five years without interruption were more likely to attend OHS than those who had insurance for four years or less (adjusted relative risk [aRR]: 1.30; 95%CI: 1.13-1.50). In addition, we carried out a sensitivity analysis by recategorizing the independent variable into three categories (never/some years/ all five years), which also showed (aRR: 1.45; 95%CI: 1.11-1.89) that participants with health insurance during all five years were more likely to have used OHS than those who never had insurance. CONCLUSION: Therefore, in the Peruvian context, health insurance affiliation was associated with greater use of OHS. The panel data used derives from a subsample of consecutive nationally representative samples, which may have led to a loss of representativeness. Furthermore, the data was collected between 2015 and 2019, prior to the onset of the COVID-19 pandemic, and insurance conditions may have changed.

Migration Status and Utilization of Healthcare Services Among Venezuelan Immigrants in Peru.

BACKGROUND: In general, migrants in illegal situations encounter a greater barrier to accessing medical care because of their migration status due to not having the required documentation to be able to obtain insurance in the receiving country. OBJECTIVE: To evaluate the association between migration status and the use of health services in the Venezuelan population residing in Peru. METHODS: Data from the second Survey Directed to the Venezuelan Population Residing in Peru (ENPOVE) of 2022 were analyzed. The dependent variable was use of health services in the last month. The exposure variable was migration status (legal/illegal). Generalized linear models of the Poisson family with link log function were used to obtain crude and adjusted prevalence ratios (aPR), for potential confounding variables. Additionally, we evaluated the association of interest, stratified by gender. FINDINGS: Data from 1569 migrants were analyzed. Participants with illegal migration status represented 32.4% (men: 24.3%; women: 36.7%); likewise, 58.1% did not use health services. Illegal migration status was associated with lower health care use (aPR: 0.75; 95%CI: 0.61-0.92). Likewise, after stratifying by sex, the association was maintained only in male migrants (aPR: 0.53; 95%CI: 0.39-0.82) but not in women (aPR: 0.84; 95%CI: 0.67-1.05). CONCLUSION: 58.1% of Venezuelan migrants in Peru did not seek medical attention despite having health problems. Having an illegal immigration status leads to a lower probability of using these services, especially in men.

Frequency, inequalities and spatial distribution of oral health services utilization in Peruvian children under twelve years of age: a population-based comparative analysis of the years 2017 and 2021.

BACKGROUND: Oral diseases pose a significant public health challenge among Peruvian children. However, oral health services utilization among them is marked by inequalities, which may have been exacerbated by the COVID-19 pandemic. The objective was to compare the frequency, inequalities, determinants of inequality, and spatial distribution in oral health services utilization in Peruvian children under 12 years of age in 2017 and 2021. METHODS: Comparative secondary data analysis from the Demographic and Family Health Survey (ENDES) for the years 2017 (38,787 minors) and 2021 (36,729 minors). Age-adjusted prevalence ratios (PR) with 95% confidence intervals (CI) were calculated to assess the change in oral health services utilization in the last 12 months between the years 2017 and 2021, stratifying by demographic and socioeconomic covariates. Inequality was assessed by decomposing the Erreygers Concentration Index (ECI) and calculating the percentage contribution to inequality of the independent variables. Spatial analysis was performed using spatial autocorrelation methods, Hot Spot Analysis, Cluster and Outlier analysis, Inverse Distance Weighting, ordinary Kriging, and Kulldorff analysis. RESULTS: The probability of Peruvian children under 12 years of age using oral health services in the last 12 months was reduced by 45% in 2021 compared to 2017. The ECI identified a significant reduction in oral health services utilization inequalities at the national level (Diff: -0.0963; p < 0.001). The main contributor to inequality was higher tutor education level (55.2% in 2017 and 82.7% in 2021). In the comparison of spatial distribution, there was a greater dispersion of the conglomerates in which the use of oral health services is concentrated in 2021. CONCLUSIONS: The frequency of oral health services utilization in the Peruvian children under 12 years of age was halved between 2017 and 2021. This problem is transversal to the entire population at the demographic and socioeconomic level. The key factor contributing to inequalities in the utilization of oral health services was the higher educational attainment of caregivers or guardians. Despite the improvement observed in inequalities and spatial distribution of the concentration of oral health services utilization, it is necessary to keep monitoring these patterns to guide decision-making.

Contextual and individual factors associated with depressive symptoms in Latin American residents from eleven cities: Multilevel analysis.

Depression is one of the most prevalent mental illnesses in the world. Its associated factors have been scarcely studied in the Latin American population. Our aim was to determine the contextual and individual factors associated with depressive symptoms (DS) in residents of 11 Latin American cities according to the 2019 CAF Survey (ECAF, acronym in Spanish). A multilevel analysis was performed to identify individual and contextual factors associated with DS. DS were measured by the short version of the Center for Epidemiological Studies Depression Scale (CES-D-10). Of the 10,206 participants, 42.0% had DS in the week prior to the survey. Regarding the individual factors studied, women (OR = 1.81, 95% CI: 1.65-1.99), smokers (OR = 1.30, 95% CI: 1.16-1.45), obese, junk food eaters more than twice a week, single people, and a greater number of people in the household were associated with greater probabilities of having DS. On the other hand, a secondary (OR = 0.77; 95% CI: 0.67-0.88) or superior educational level (OR = 0.58; 95% CI: 0.50-0.68) were associated as protective factors. Regarding contextual factors, higher contamination levels (OR = 1.07, 95% CI: 1.01-1.13) were associated with DS. Our study reports associations between individual and environmental factors and DS in residents of Latin America. These findings will allow the adoption of the necessary measures for decision-making and research to face this growing problem in developing countries.

Physical abuse in childhood and intimate partner violence in Peruvian women: A population-based survey, 2019.

Intimate partner violence (IPV) is a global health problem and a violation of individual rights. The objective of this study was to assess the association between physical child abuse and current IPV in women of childbearing age in Peru. An analytical cross-sectional analysis of the data from the 2019 Demographic and Family Health Survey was carried out. IPV was constituted by emotional, physical and sexual violence, while physical child abuse was constructed from variables related to physical punishment that women of childbearing age experienced during childhood. Poisson's family generalized linear models were used for the crude and adjusted analyses to determine the association between physical child abuse and IPV. Data from a total of 21,518 women of childbearing age were included. 67.1% of women experienced physical abuse in childhood, while 57.7% experienced intimate partner violence. After adjusting for the characteristics of the woman, the partner or husband, marriage or relationship and the home, it was observed that having experienced physical abuse during childhood increased the probability of experiencing emotional (adjusted prevalence ratio [aPR] 1.15; 95% confidence interval [CI]: 1.09-1.21), physical (aPR 1.33; 95% CI: 1.20-1.47), sexual (aPR 1.57; 95% CI: 1.26-1.96) and any type of violence (aPR 1.15; 95% CI: 1.09-1.21) in adulthood. In conclusion, physical abuse during childhood is a public health issue in Peru. This study shows that women aged 15 to 49 who experienced physical abuse in childhood are more likely to experience intimate partner violence.

Prevalence of hepatitis C virus infection in patients with end-stage renal disease in Latin America and the Caribbean: a systematic review and meta-analysis.

AIM: To estimate the prevalence of hepatitis C virus (HCV) infection in patients with end-stage renal disease (ESRD) undergoing hemodialysis in Latin America and the Caribbean (LAC). MATERIALS AND METHODS: Observational studies published in Spanish, Portuguese, and English language by November 25, 2021, in PubMed, Embase, Web of Science, Scopus, SciELO, and LILACS were selected by two reviewers according to predefined eligibility criteria. Study quality was assessed using the US National Heart, Lung and Blood Institute tool for observational cohort and cross-sectional studies. A meta-analysis of proportions was performed using a random-effects model based on the DerSimonian and Laird method, using R. PROSPERO N°: CRD42018107403. RESULTS: A total of 20 studies were included in the narrative synthesis (15 from Brazil, two from Cuba, two from Argentina, and one from Peru). Only 17 studies were included in the meta-analysis (13 from Brazil, two from Argentina, one from Cuba, and one from Peru). The overall prevalence of HCV in ESRD patients undergoing hemodialysis in LAC was 11.3% (95% confidence interval [CI]: 8.9% - 13.9%; I2: 99 %). In Brazil and Argentina, the prevalence was 6% and 26.1%, respectively. Prevalence after excluding poor-quality studies was 10.7%. CONCLUSION: The prevalence of HCV in ESRD patients undergoing hemodialysis in LAC was 11.3%. The implementation of infection control measures in hemodialysis centers in LAC is required. It is also necessary to increase the number of studies on the subject in the ESRD population in most LAC countries.

Outcomes in ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention or pharmacoinvasive strategy in a Latin American country.

OBJECTIVE: The primary percutaneous coronary intervention (PPCI) is the preferred reperfusion strategy for ST-segment elevation myocardial infarction (STEMI). The pharmacoinvasive strategy (PIs) is a reasonable alternative when prompt PPCI is not possible, especially in resource-limited regions. We aimed to compare PPCI versus PIs outcomes in Peru. METHODS: This was a retrospective cohort study based on the second Peruvian Registry of STEMI (PERSTEMI II). We compared the characteristics, in-hospital outcomes and 30-day mortality of patients undergoing PPCI during the first 12 h and those receiving a PIs. A propensity score-matched analysis was conducted to compare the effects of each treatment strategy on clinical outcomes. RESULTS: PIs patients were younger than PPCI patients, had a shorter first medical contact time, first medical contact to reperfusion time, and total ischemic time until reperfusion. Successful PCI was more frequent in the PIs group (84.4% vs. 71.1%, p = 0.035). There were no differences between PIs and PPCI in terms of total in-hospital mortality (5.2% vs. 6.6%, p = 0.703), cardiovascular mortality (4.2% vs. 5.3%, p = 0.735), cardiogenic shock (8.3% vs. 13.2%, p = 0.326), heart failure (19.8% vs. 30.3%, p = 0.112), or major bleeding (0% vs. 2.6%, p = 0.194). In the propensity score-matched analysis, the rates of cardiovascular mortality, postinfarction heart failure and successful reperfusion were similar. CONCLUSIONS: In this real-world study, no differences were found in the in-hospital outcomes between patients with STEMI who received PIs or PPCI.

Socio-economic inequalities in the consumption of fruits and vegetables in Peru between 2014 and 2019.

OBJECTIVE: To estimate the prevalence and socio-economic inequalities in adequate consumption of fruits and vegetables in Peru between 2014 and 2019. DESIGN: Analytical cross-sectional study. The outcome variable was adequate consumption of fruits and vegetables, defined as the consumption of five or more servings of fruits and vegetables per d (yes/no). We used concentration curves and Erreygers concentration index to describe socio-economic inequalities and a microeconometric approach to determine the contribution of each variable to inequality. SETTING: Peru. PARTICIPANTS: Data from Peruvians aged 18 years or older collected by the Demographic and Family Health Survey. RESULTS: The prevalence of adequate fruit and vegetable consumption did not change between 2014 (10·7 %; 95 % CI (10·0, 11·4)) and 2019 (11 %; 95 % CI (10·4, 11·7)). We found socio-economic inequalities in the adequate consumption of fruits and vegetables, with wealthier individuals having a higher prevalence of adequate consumption compared to poorer individuals in 2014 (19·2 % v. 3·5 %) and 2019 (18·6 % v. 4·7 %). The decomposition analysis found that education, urban areas and being wealthy were the main factors associated with socio-economic inequality in adequate fruit and vegetable consumption, being structural problems of society. CONCLUSION: Despite the current regulations on healthy eating in Peru, adequate consumption of fruits and vegetables remains low, and there are socio-economic inequalities between the poorest and wealthiest individuals. Our findings suggest that more efforts are needed to increase the intake and assess the disparities in adequate fruit and vegetable consumption.

Geographic and socioeconomic inequalities in cesarean birth rates in Peru: A comparison between 2009 and 2018.

BACKGROUND: There is a global concern about the high rates of cesarean birth (CB). This study aimed to investigate the geographic and socioeconomic inequalities in CB rates in the Peruvian population. METHODS: We conducted a population-based study using the Peruvian Demographic and Family Health Surveys (ENDES, the Spanish acronym for Encuesta Demográfica y de Salud Familiar) between 2009 and 2018. ENDES reported data from births registered in the five years preceding survey execution. For the years 2009 (n = 10 289) and 2018 (n = 23 077), we calculated the weighted rates of CB among variables such as natural geographic domain (Coast, Andean, or Amazon), area of residence (rural or urban), wealth index quintile (quintile 1 is poorest, and quintile 5 is richest), and educational level. To assess inequalities, we calculated the concentration index (CIs), the slope index of inequality (SII), and the relative index of inequality (RII). RESULTS: The CB rates by year were 21.4% (95% confidence interval [CI]: 20.0-22.9) in 2009 and 34.5% (95% CI: 33.4-35.5) in 2018. Women living in urban and coastal regions and with a higher education level had the highest CB rates. All the CIs were positive, reflecting a prowealthy inequality in CB rates, and both SII and RII were positive, indicating a gap between the use of cesarean in women in the higher wealth quintile compared with those in the lower quintile. CONCLUSIONS: Cesarean birth rates have increased by 60% during the last decade in Peru. The richest wealth quintiles had the highest CB rates during the study years, which were well above global recommendations.

Global Research Trends in the Latarjet Procedure: A Bibliometric and Visualized Study.

Background and Objectives: Latarjet is among the procedures indicated to treat shoulder instability, producing excellent results, including low instability rates and high patient satisfaction. The aim of this study was to report the characteristics of scientific articles that address the subject of the Latarjet procedure through the use of bibliometric analysis. Materials and Methods: Bibliographic searches were performed for original articles published in journals indexed by the Web of Science database until 2021, with no language restrictions. Results: A total of 668 articles published in 87 journals were included. The first publication was in 1981; the most registered publications were in 2018 and 2021 (89 articles), with an annual percentage growth rate of 11.9. Provencher MT was the author with the most published articles, and the institutional affiliation with the most original articles was the Steadman Philippon Research Institute. The most cited article was a study by Burkhart and Beer, and the scientific journal with the most publications on the subject was the Journal of Shoulder and Elbow Surgery. Most published studies included keywords such as dislocation, instability, and meta-analysis. Conclusion: There has been a sustained increase in original articles on the Latarjet procedure. However, the greatest growth in articles has occurred during the last decade, demonstrating the considerable interest among the world scientific community.

Mouthrinses and SARS-CoV-2 viral load in saliva: a living systematic review.

Objective To conduct a living systematic review of the clinical evidence about the effect of different mouthrinses on the viral load of SARS-CoV-2 in the saliva of infected patients.Methods This study was reported using the PRISMA guidelines. An electronic search was conducted in seven databases and preprint repositories. We included human clinical trials that evaluated the effect of mouthrinses with antiseptic substances on the viral load of SARS-CoV-2 in the saliva of children or adults, who tested positive for SARS-CoV-2 by reverse transcriptase-polymerase chain reaction (RT-PCR). The risk of bias was assessed using the ROBINS-I tool. PROSPERO registration number: CRD42021240561.Results Five studies were included (n = 66 participants). Study participants underwent oral rinses with hydrogen peroxide (H2O2) at 1%, povidone-iodine (PI) at 0.5% or 1%, chlorhexidine gluconate (CHX) at 0.2% or 0.12%, cetylpyridinium chloride (CPC) at 0.075%, and Linolasept. Only one study included a control group with sterile water. Three of the studies identified a reduction in viral load in saliva after the use of mouthrinses with PI (up to three hours), CHX (up to four hours), or Linolasept mouthwash (up to six hours). One study reported a statistically significant reduction after the use of mouthrinses with CPC or PI vs water (up to six hours) and one study reported a non-significant reduction in viral load after the use of H2O2 rinses.Conclusions According to the present systematic review, the effect of mouthrinses on SARS-CoV-2 viral load in the saliva of COVID-19 patients remains uncertain. Evidence from well-designed randomised clinical trials is required for further and more objective evaluation of this effect.

Trends and patterns of the double burden of malnutrition (DBM) in Peru: a pooled analysis of 129,159 mother-child dyads.

BACKGROUND: This study aims to evaluate trends of DBM in Peru over the last 20 years. METHODS: Using individual-level data collected in nationally representative household surveys from Peru between 1996 and 2017, we analysed trends in the prevalence and patterning of the DBM. We classified the nutritional status of children and their mothers as undernourished (either underweight, stunted or wasted for children), normal, overweight or obese. Children classified as experiencing the DBM were those undernourished and living with an overweight or obese mother. We also fitted logistic regression models to evaluate the probability of children having an overweight/obese mother across subgroups of socioeconomic status, place of residence and education. RESULTS: The overall percentage of children experiencing the DBM in 2016 was 7%, and constitutes ~203,600 children (90% of whom were stunted). Between 1996 and 2016, undernourished children have seen the largest relative increase in the risk of having an overweight mother (31% vs. 37%) or obese mother (6% vs. 17%); however, due to the substantial decrease in the absolute number of undernourished children, the DBM has not grown. Moreover, all children, irrespective of their own nutritional status, are now more likely to live with an overweight or obese mother, a consistent pattern across wealth, location and education subgroups, and all regions of Peru. CONCLUSIONS: DBM prevalence in Peru has decreased, although the number of DBM cases is estimated to be above 200,000. In addition, all children are now more likely to live with overweight or obese mothers. The basic pattern has shifted from one of undernourished children whose mothers have a 'normal' BMI, to one where now most children have a 'normal' or healthy anthropometric status, but whose mothers are overweight or obese. This suggest that Peru is on the cusp of a major public health challenge requiring significant action.

Inequalities in access to safe drinking water in Peruvian households according to city size: an analysis from 2008 to 2018.

BACKGROUND: Peru is one of the countries with the lowest percentage of population with access to safe drinking water in the Latin American region. This study aimed to describe and estimate, according to city size, socioeconomic inequalities in access to safe drinking water in Peruvian households from 2008 to 2018. METHODS: Secondary analysis of cross-sectional data using data from the 2008-2018 ENAHO survey. Access to safe drinking water, determined based on the presence of chlorinated water supplied by the public network, as well as socioeconomic variables were analyzed. A trend analysis from 2008 to 2018, and comparisons between 2008 versus 2018 were performed to understand and describe changes in access to safe drinking water, according to city size. Concentration curves and Erreygers concentration index (ECI) were estimated to measure inequalities in access to safe drinking water. RESULTS: In 2008, 47% of Peruvian households had access to safe drinking water, increasing to 52% by 2018 (p for trend < 0.001). For small cities, access to safe drinking water did not show changes between 2018 and 2008 (difference in proportions - 0.2 percentage points, p = 0.741); however, there was an increase in access to safe drinking water in medium (difference in proportions 3.3 percentage points, p < 0.001) and large cities (difference in proportions 12.8 percentage points, p < 0.001). The poorest households showed a decreasing trend in access to safe drinking water, while the wealthiest households showed an increasing trend. In small cities, socioeconomic inequalities showed an increase between 2008 and 2018 (ECI 0.045 and 0.140, p < 0.001), while in larger cities, socioeconomic inequality reduced in the same period (ECI: 0.087 and 0.018, p = 0.036). CONCLUSIONS: We report a widening gap in the access to safe drinking water between the wealthiest and the poorest households over the study period. Progress in access to safe drinking water has not been equally distributed throughout the Peruvian population. Promoting and supporting effective implementation of policies and strategies to safe drinking water, including equity-oriented infrastructure development and resource allocation for most vulnerable settings, including emerging small cities, is a priority.

Factors associated with the consumption of table salt with inadequate iodine concentrations: a population analysis at a Peruvian household level.

OBJECTIVE: Iodine deficiency is a public health problem, especially in Peru, where it affects women of childbearing age and school-age children. The objective of the study was to conduct a household-level analysis of the factors associated with the consumption of table salt with inadequate amounts of iodine in Peru. DESIGN: Analytical cross-sectional study using Peruvian household-level data from the Demographic and Family Health Survey. Table salt iodine concentrations were considered as the dependent variable ('inadequate' with iodine levels <30 PPM and 'adequate' with levels ≥30 PPM). The association between iodine concentrations in salt and independent variables was evaluated using crude and adjusted log-binomial regression models. SETTING: Peru. PARTICIPANTS: A total of 25 007 households were included. RESULTS: In Peru, 21·8 % households had inadequate table salt iodine concentrations. Belonging to the poorer and poorest wealth index, living in the Highlands natural region, and living with women of childbearing age with native mother tongue were identified as factors associated with inadequate iodine concentrations in table salt. CONCLUSIONS: There is an urgent need to ensure that table salt with adequate iodine concentrations is available for poor populations, residents of the Highlands and households with ethnic presence. Likewise, it is necessary to promote good storage practices, greater regulation/law enforcement and better monitoring of the companies that manufacture or sell this product. Furthermore, the population needs to be informed of the disorders associated with iodine deficiency.

Health and Economic Impact of Health Warnings and Plain Tobacco Packaging in Seven Latin American Countries: Results of a Simulation Model.

INTRODUCTION: The burden of disease attributable to tobacco use in Latin America is very high. Our objective was to evaluate the 10-year potential impact of current legislation related to cigarette packaging and warnings and expected effects of moving to a higher level of strategies implementing cigarette plain packaging on health and cost outcomes in Argentina, Bolivia, Brazil, Chile, Colombia, Mexico, and Peru, using a microsimulation model. AIMS AND METHODS: We used a probabilistic state-transition microsimulation model, considering natural history, costs, and quality of life losses associated with main tobacco-related diseases. We followed up individuals in hypothetical cohorts and calculated health outcomes annually to obtain aggregated long-term population health outcomes and costs. We performed a literature review to estimate effects and analyzed studies and information from ministries, relevant organizations, and national surveys. We calibrated the model comparing the predicted disease-specific mortality rates with local statistics. RESULTS: Current graphic warnings already in place in each country could avert, during 10 years, 69 369 deaths and 638 295 disease events, adding 1.2 million years of healthy life and saving USD 5.3 billion in the seven countries. If these countries implemented plain packaging strategies, additional 155 857 premature deaths and 4 133 858 events could be averted, adding 4.1 million healthy years of life and saving USD 13.6 billion in direct health care expenses of diseases attributable to smoking. CONCLUSIONS: Latin American countries should not delay the implementation of this strategy that will alleviate part of the enormous health and financial burden that tobacco poses on their economies and health care systems. IMPLICATIONS: Tobacco smoking is the single most preventable and premature mortality cause in the world. The Framework Convention on Tobacco Control, supported by the World Health Organization, introduced a package of evidence-based measures for tobacco control. This study adds evidence on the potential health effects and savings of implementing cigarette plain packaging in countries representing almost 80% of the Latin American population; findings are valuable resources for policy makers in the region.

Cut-off points of anthropometric markers associated with hypertension and diabetes in Peru: Demographic and Health Survey 2018.

OBJECTIVE: To determine the optimal anthropometric cut-off points for predicting the likelihood ratios of hypertension and diabetes in the Peruvian population. DESIGN: A cross-sectional study was performed to establish cut-off values for body mass index (BMI), waist circumference (WC), waist:height ratio (WHtR) and Conicity index (C-index) associated with increased risk of hypertension and diabetes. Youden's index (YIndex), area under the curve (AUC), sensitivity and specificity were calculated. SETTING: Peruvian households. PARTICIPANTS: Peruvian population over the age of 18 years. RESULTS: A total of 31 553 subjects were included, 57 % being women. Among the women, 53·06 % belonged to the 25- to 44-year-old age group [mean age: 41·66 in men and 40·02 in women]. The mean BMI, WHtR and C-index values were higher in women 27·49, 0·61, 1·30, respectively, while the mean WC value was higher in men 92·12 cm (sd ± 11·28). The best predictors of hypertension in men were the WHtR (AUC = 0·64) and the C-index (AUC = 0·64) with an optimal cut-off point of 0·57 (YIndex = 0·284) and 1·301 (YIndex = 0·284), respectively. Women showed an AUC of 0·63 and 0·61 in the WHtR and C-index, respectively, with an optimal cut-off of 0·61 (YIndex = 0·236) and 1·323 (YIndex = 0·225). The best predictor for diabetes was the C-index: with an AUC = 0·67 and an optimal cut-off of 1·337 (YIndex = 0·346) for men and an AUC = 0·66 and optimal cut-off of 1·313 (YIndex = 0·319) for women. CONCLUSIONS: Our findings show that in Peruvian adults, the WHtR and the C-index have the strongest association with hypertension in both sexes. Likewise, the C-index had the strongest association with diabetes.

Peruvian scientific production on Helicobacter pylori: a bibliometric analysis.

OBJECTIVE: To evaluate the Peruvian scientific production on Helicobacter pylori. MATERIALS AND METHODS: Bibliometric analysis of original articles published until September 8, 2020, in journals indexed in PubMed, Scopus, Web of Science, LILACS, and SciELO. Bibliometric indicators were obtained. Likewise, analysis of the co-citation of authors and co-occurrence of terms with the terms included in the title and the abstract of publications was performed. RESULTS: Data from 180 original articles were analyzed. An increase in the number of articles on H. pylori was found (R2 = 0.64, an average annual growth rate of 8.01%). A total of 777 authors were identified, with an average number of articles per author of 0.18, and a collaboration index of 5.64. The average number of citations per original article was 1.91. The Universidad Peruana Cayetano Heredia was the institution with the highest number of original articles (63.2%). The analysis of co-occurrence of terms found terms related to gastric cancer during the whole study period and, for recent years, terms related to the treatment of H. pylori infection and water sources. CONCLUSION: There is an increase in Peruvian production in original articles on H. pylori. In recent years, the study of the eradication of H. pylori and the transmission of the agent from water sources have been topics of interest.

Rural and urban disparities in oral hygiene practices among Peruvian children aged less than 12 years: Demographic and Family Health Survey 2018.

INTRODUCTION: The adoption of adequate oral hygiene practices is important for the maintenance of good oral health in children. Rural-urban differences in the achievement of this important issue in Peru remain unknown. The objective of this study was to assess rural-urban differences in the proportion of adequate oral hygiene practices in Peruvian children aged less than 12 years, as well as associated sociodemographic factors. METHODS: This was a cross-sectional study of the 2018 Peruvian Demographic and Family Health Survey. Data from 41 330 children aged 1-11 years and their caregivers with complete information on oral hygiene practices were included in the study. Crude and adjusted prevalence ratios and 95% confidence intervals were estimated as measures of association between adequate oral hygiene practices (defined as toothbrushing two or more times a day, having a toothbrush for individual use and changing toothbrushes every 3 months) and sociodemographic variables. RESULTS: The prevalence of adequate oral hygiene practices was 38.3% in the rural area and 57.3% in urban areas. The greatest rural-urban disparities for adequate oral hygiene practices were observed in the age group of 6-11 years (43.4% v 64.1%), those in families in which the head of the household had no formal education (28.1% v 47.3%) or primary education (36.8% v 53.0%), those who had used dental services in the previous 6 months (46.4% v 64.4%) and those residing in the highlands (31.5% v 48.2%). All independent variables were significantly associated with adequate oral hygiene practices in rural areas, except for the jungle region variable and the richest wealth index. CONCLUSION: Four out of ten Peruvian children living in rural areas perform adequate oral hygiene practices compared to six out of ten children in urban areas. Furthermore, inequalities in the adoption of oral hygiene practices favor urban children according to sociodemographic factors. Strengthening of oral health promotion strategies is urgently needed in order to decrease inequalities in the adoption of adequate oral hygiene in children living in rural areas of Peru and countries with similar sociodemographic characteristics.
