Alta prevalencia en el consumo de tabaco y desigualdades en población Lenca, Intibucá, Honduras, 2015 / High prevalence of tobacco consumption and inequalities in Lenca population, Intibucá, Honduras, 2015

Antecedentes: Aproximadamente un sexto de la población mundial tiene el hábito de fumar para una prevalencia de 24%. La OMS considera que, de no cambiar las tendencias durante el siglo XXI, el tabaco será responsable de la muerte prematura de mil millones de personas. Objetivo: Determinar la prevalencia del consumo de tabaco y la medición de desigualdades socioeconómicas en la población Lenca, Municipio de Intibucá, Intibucá, Honduras, 2015. Métodos: Estudio descriptivo transversal con análisis de asociación. Se aplicó formulario estructurado para recolectar datos generales, sociodemográficos y tabaquismo, previo consentimiento informado. Dependencia al tabaco fue evaluada con test Faguerström. Se prepararon bases de datos en Epi-info-7 y SPSS-18. Se calcularon razones de disparidad (OR). Resultados: De un total de 602 entrevistados,se identificaron 167 fumadores para una prevalencia de consumo de tabaco de 27.7%. El 76.6% (128) de fumadores tuvo dependencia baja a nicotina y 23.4% (39) dependencia moderada. La media de ingreso familiar mensual fue USD$193 en fumadores y USD$168 en no fumadores. El 40.1% (67) de fumadores gastó mensualmente en tabaco un mínimo de USD$95. No se encontró relación entre consumo de tabaco e ingreso familiar mensual (OR=0.87, IC95% 0.7-1.0) ni con analfabetismo (OR=1.20, IC95% 0.7-2.0). Discusión: No se observaron diferencias significativas entre consumo de tabaco y las variables socioeconómicas, se encontró una elevada prevalencia de consumo de tabaco en esta población en relación con otros estudios realizados en el país. Los resultados apoyan la necesidad de políticas enfocadas en prevención del tabaco en indígenas...(AU)

Socioeconomic predictors of dietary patterns among Guatemalan adults.

OBJECTIVES: We aimed to assess the associations of socioeconomic factors with dietary patterns in a Guatemalan population. METHODS: Cross-sectional data of 1076 participants (42 % men, mean age 32.6 ± 4.2 years) collected between 2002 and 2004 in four rural villages in Guatemala. Dietary patterns were derived using principal component analysis. Chi-square and Poisson regression models were used to assess associations between socioeconomic factors and dietary patterns. RESULTS: Three dietary patterns were identified: "Western" (high in processed foods), "traditional" (high in traditional foods) and "coffee and sugar", explaining 11, 7 and 6 % of the variance, respectively. Annual expenditures were associated with a higher adherence to the "Western" pattern: prevalence ratios [(PR) (95 % confidence interval)] 1.92 (1.17-3.15) for the highest vs. lowest expenditure group in men and 8.99 (3.57-22.64) in women. A borderline significant (p = 0.06) negative association was found between the "traditional" pattern and higher household expenditures [0.71 (0.49-1.02) in men] and with schooling [0.23 (0.05-1.02)] in women (p = 0.05). CONCLUSIONS: Dietary patterns in Guatemala are predicted by socioeconomic factors. In particular, high annual expenditures are associated with a more westernized, less traditional diet.

Relative Validity of Three Food Frequency Questionnaires for Assessing Dietary Intakes of Guatemalan Schoolchildren.

OBJECTIVE: To determine the relative validity of three food frequency questionnaires (FFQs) compared with results from 24-hour dietary recalls for measuring dietary intakes in Guatemalan schoolchildren. DESIGN: A cross-sectional study of primary caregivers (mothers or grandmothers) of 6-11 year-old children. Caregivers completed one of three constructed FFQs to measure the child's dietary consumption in the last week: FFQ1 did not incorporate portion sizes; FFQ2 provided portion sizes; and FFQ3 incorporated pictures of median portion sizes. During the same week, each caregiver also completed three 24-hour dietary recalls. Results from the FFQ were compared with corresponding results from the 24-hour dietary recalls. SETTING: Santa Catarina Pinula, peri-urban Guatemala City. SUBJECTS: Caregivers (n = 145) of 6-11 year-old children: 46 completed FFQ1, 49 completed FFQ2, and 50 completed FFQ3. RESULTS: The mean values for all nutrients obtained from the 24-hour dietary recall were lower than for those obtained from the FFQs, excluding folic acid in FFQ3, cholesterol and zinc in FFQ2, and cholesterol, folic acid, magnesium, potassium, sodium, and zinc in FFQ1. Energy-adjusted Pearson correlation coefficients ranged from 0.07 (protein) to 0.54 (cholesterol) for FFQ1 and from 0.05 to 0.74 for FFQ2 and FFQ3. Agreement by both methods (FFQ and 24-hour dietary recalls) of classifying children into the same or adjacent quartiles of energy-adjusted nutrient consumption ranged from 62.0% for cholesterol to 95.9% for vitamin B12 across all three FFQs. CONCLUSIONS: Our FFQs had moderate to good relative validity in measuring energy and nutrient intakes for 6-11 year-old Guatemalan children. More evidence is needed to evaluate their reproducibility and applicability in similar populations.

Socioeconomic determinants of dietary patterns in low- and middle-income countries: a systematic review.

BACKGROUND: In high-income countries, high socioeconomic status (SES) is generally associated with a healthier diet, but whether social differences in dietary intake are also present in low- and middle-income countries (LMICs) remains to be established. OBJECTIVE: We performed a systematic review of studies that assessed the relation between SES and dietary intake in LMICs. DESIGN: We carried out a systematic review of cohort and cross-sectional studies in adults in LMICs and published between 1996 and 2013. We assessed associations between markers of SES or urban and rural settings and dietary intake. RESULTS: A total of 33 studies from 17 LMICs were included (5 low-income countries and 12 middle-income countries; 31 cross-sectional and 2 longitudinal studies). A majority of studies were conducted in Brazil (8), China (6), and Iran (4). High SES or living in urban areas was associated with higher intakes of calories; protein; total fat; cholesterol; polyunsaturated, saturated, and monounsaturated fatty acids; iron; and vitamins A and C and with lower intakes of carbohydrates and fiber. High SES was also associated with higher fruit and/or vegetable consumption, diet quality, and diversity. Although very few studies were performed in low-income countries, similar patterns were generally observed in both LMICs except for fruit intake, which was lower in urban than in rural areas in low-income countries. CONCLUSIONS: In LMICs, high SES or living in urban areas is associated with overall healthier dietary patterns. However, it is also related to higher energy, cholesterol, and saturated fat intakes. Social inequalities in dietary intake should be considered in the prevention and control of noncommunicable diseases in LMICs.
