RESUMEN
BACKGROUND: The study of dietary patterns in older adults (OA) and their association with geriatric syndromes (GS) is scarce in Latin America. OBJECTIVE: To describe the association of dietary patterns with GS in the Mexican older adult population, using data from the 2018-19 National Health and Nutrition Survey. METHODS: Dietary data were collected from 3,511 adults (≥60 years of age, both sexes) using a semi-quantitative food frequency questionnaire. Dietary patterns were derived by principal component analysis based on the consumption of 162 foods from 24 food groups. The GS studied were: frailty, depressive symptoms (DS), low appendicular skeletal muscle mass (ASMM); additionally, we studied inflammation (serum CRP>5 mg/L). Logistic regression models were used. RESULTS: Four major dietary patterns were identified: a) "Western", b) "Prudent", c) "Soups", and d) "Traditional". The middle and higher tertiles of the "Prudent" pattern were associated with lower odds of DS (OR 0.71, p = 0.04; and OR 0.61, p = 0.008), respectively. The second tertile of the "Soups" pattern was associated with lower odds of low ASMM (OR 0.68, p = 0031) and inflammation (OR 0.58, p = 0.022). The highest tertile of the "Traditional" pattern was associated with low ASMM (OR 1.55, p = 0.008) and lower odds of inflammation (OR 0.69, p = 0.044). No association was found between the "Western" dietary pattern and GS. CONCLUSIONS: Three of four major dietary patterns were associated with GS in older Mexican adults. Further studies are needed to address strategies to improve diet quality in this age group and its association with health and functional outcomes.
RESUMEN
BACKGROUND AND AIMS: Breakfast consumption could have a synchronizer role in chronobiological functions. Across observational studies, the assessment of breakfast frequency consumption is heterogeneous, therefore consensus on the relation between of weekly frequency of breakfast consumption and the risk of diabetes is unclear. We examined the relation between weekly breakfast frequency consumption and the incidence of diabetes in middle-age women. METHODS AND RESULTS: Since baseline (2006-2008) we prospectively followed 71,373 women from the Mexican Teachers' Cohort. Participants were classified according to breakfast consumption frequency of 0, 1-3, 4-6, or 7 days/week. Diabetes was identified by self-report and clinical-administrative databases. We used Cox proportional hazards multivariable models to estimate hazard ratios (HR) and 95% confidence intervals (CI) for breakfast frequency and diabetes adjusting for covariates. Stratified analyses were performed for age, birth weight, ethnicity, and physical activity. We identified 3613 new diabetes cases between baseline and 2014. The prevalence of daily breakfast consumers was 25%. The median follow-up was 2.2 years, interquartile range 1.8-3.8 years. Relative to women who skipped breakfast, those who consumed breakfast every day had a 12% lower risk of diabetes (multivariable HR = 0.88; 95% CI 0.78, 0.99; p-trend = 0.0018). One additional day per week of breakfast was associated with a lower risk of diabetes (HR = 0.98; 95% CI 0.97, 0.99). In stratified analysis, the observed inverse relation appeared to be stronger in women aged ≥40 years and in indigenous women. CONCLUSIONS: Breakfast frequency was inversely associated with the incidence of diabetes independently of lifestyle factors. Regular breakfast consumption may be a potential component of diabetes prevention.
RESUMEN
Worldwide, as well as in Mexico, the leading cause of death is cardiovascular disease (CVD). Hypertension is the main risk factor for CVD; about 50% of the adult population suffers from this condition. High sodium (Na) intake combined with low potassium (K) intake can trigger cardiovascular disorders such as high blood pressure (BP). The aim of this study was to estimate the mean excretion of Na and K in Mexican adults using a spot urine sample, and its association with cardiovascular disorders. Information on 2,778 adults, 20-59 years of age, who participated in ENSANUT-2016 was analyzed. Na and K were estimated using Tanaka formulae. Biomarkers such as glucose, total cholesterol, triglycerides, HDL cholesterol and LDL cholesterol, and anthropometry were measured. Mean Na was 3,354 mg/day (95%CI: 3,278, 3,429), 1,440 mg/day of K (95%CI: 1,412, 1,469), and the Na-K ratio was 2.4. The excretion of Na was greater in adults with high BP (3,542 mg/day) compared to those with normal BP (3,296 mg/day). In adults with hypertension, excretion of K was 10% greater (1,534 mg/day) than in adults with normal BP (1,357 mg/day). In adults with moderate reduction of renal function, Na excretion was 22% less (2,772 mg/day) than in adults with normal kidney function (3,382 mg/day). The results of this study show that the cardiovascular health of Mexican adults is at risk, as they showed high Na excretion and low K excretion.
RESUMEN
BACKGROUND: The consumption of sugar-sweetened beverages (SSB), of which Mexico is a large consumer, has been associated with the risk of breast cancer. We assessed the association between SSBs consumption and breast cancer risk in pre- and postmenopausal women. METHODS: We performed a multicenter population-based case-control study in Mexico City, Monterrey, and Veracruz. We recruited 1,000 cases and 1,074 controls; all participants were pre- or postmenopausal women between 35 and 69 years of age. Diet before symptoms onset was assessed using a food frequency questionnaire. We conducted a multivariable-adjusted conditional logistic regression analysis stratified by menopausal status. RESULTS: For premenopausal women, after adjusting for matching characteristics, total energy intake and all potential confounders, the odds of having breast cancer in women who drank one or more SSBs servings per day showed 1.78 times the odds of those who drank one or fewer SSBs servings per month [OR = 1.78; 95% confidence interval (CI), 1.06-3.01]. For postmenopausal women, the corresponding model was not statistically significant (OR = 1.38, 95% CI, 0.84-2.25). We also observed higher consumption of SSBs among pre- than in postmenopausal women (23.3% and 17.4%, respectively among controls in the highest consumption category (≥1 per day). CONCLUSIONS: Our results suggest that SSBs consumption increases the risk of developing breast cancer, particularly in premenopausal women. IMPACT: Given the consumption of SSBs, of which Mexico is a large consumer, these results can support public policies to discourage the consumption of SSBs.

Vitamin D (VD) deficiency (serum 25(OH)D < 50 nmol/L) affects 27.3% of preschool children in Mexico. The purpose of this study was to assess the effect of vitamin D supplementation at different doses on serum 25(OH)D concentrations in preschool children. In a randomized control trial, 222 children 12-30 months old were randomly assigned to one of four treatment groups: (1) Vitamin D2 (Ergocalciferol) 400 IU/day (n = 56); (2) Vitamin D2 (Ergocalciferol) 800 IU/day (n = 55); (3) Vitamin D3 (Cholecalciferol) 1000 IU/day (n = 56); or (4) multiple micronutrients (MM) non-VD (n = 55). Supplements were given five days/wk for three months. Serum 25(OH)D was measured at baseline and after three months. At baseline, mean serum 25(OH)D was 58.9 ± 12.6 nmol/L and 23.4% were VD-deficient. There was a statistically significant increase in serum concentrations of 25(OH)D (range across groups: +8.2 to +17.3 nmol/L). Additionally, the prevalence of vitamin D deficiency decreased after three months: for D2 400 IU, -9.0%; for D2 800 IU, -11.0%; for D3 1000 IU, -18.0%; and for MM non-VD, -2.8% (p < 0.05). No adverse effects were observed. VD supplementation for three months was effective for increasing serum 25(OH)D concentrations and for reducing VD deficiency in preschool children. The highest efficacy was observed by giving 1000 IU D3/d.

Population studies have demonstrated an association between sodium and potassium intake and blood pressure levels and lipids. The aim of this study was to describe the dietary intake and contribution of sodium and potassium to the Mexican diet, and to describe its association with nutrition status and clinical characteristics. We analyzed a national survey with 4219 participants. Dietary information was obtained with a 24-h recall. Foods and beverages were classified according to level of processing. The mean intake (mg/d) of Na was 1512 in preschool children, 2844 in school-age children, 3743 in adolescents, and 3132 in adults. The mean intake (mg/d) of K was 1616 in preschool children, 2256 in school-age children, 2967 in adolescents, and 3401 in adults. Processed and ultra-processed foods (UPF) contribute 49% of Na intake in preschool children, 50% in school-age children, 47% in adolescents, and 39% in adults. Adults with high Na intake had lower serum concentrations of cholesterol, HDL-c, and LDL-c. A significant proportion of the Mexican population has a high intake of Na (64-82%) and low K (58-73%). Strategies to reduce Na and increase K intake need to reduce the possibility of having high BP and serum lipid disturbances.

Anemia in older adults is a growing public health issue in Mexico; however, its etiology remains largely unknown. Vitamin A deficiency (VAD) and vitamin D deficiency (VDD) have been implicated in the development of anemia, though by different mechanisms. The aim of this study is to analyze the etiology of anemia and anemia-related factors in older Mexican adults. This is a cross-sectional study of 803 older adults from the southern region of Mexico in 2015. The anemia etiologies analyzed were chronic kidney disease (CKD), nutritional deficiencies (ND), anemia of inflammation (AI), anemia of multiple causes (AMC) and unexplained anemia (UEA). VAD was considered to be s-retinol ≤ 20 µg/dL, and VDD if 25(OH)D < 50 nmol/L. IL-6 and hepcidin were also measured. Multinomial regression models were generated and adjusted for confounders. Anemia was present in 35.7% of OA, independent of sex. UEA, CKD, AI and ND were confirmed in 45%, 29.3%, 14.6% and 7% of older adults with anemia, respectively. Hepcidin and log IL-6 were associated with AI (p < 0.05) and CKD (p < 0.001). VAD was associated with AI (p < 0.001), and VDD with ND and AMC (p < 0.05). Log-IL6 was associated with UEA (p < 0.001). In conclusion, anemia in older adults has an inflammatory component. VAD was associated to AI and VDD with ND and AMC.

BACKGROUND: vitamin D (VD) may be a protective factor for retinoblastoma, though no temporal association has been reported during pregnancy or the child's first year of life. Serum VD concentrations are determined by both distal (DF) and proximal factors (PF). OBJECTIVE: To identify if DF and PF can predict VD insufficiency (VDI) and VD deficiency (VDD) in women of childbearing age; and to test whether maternal exposure to DF and PF during pregnancy and a child's exposure during the first 11.9 months postpartum are associated with sporadic retinoblastoma (SRb) in children. METHODS: This is a secondary analysis of data from the Epidemiology of SRb in Mexico (EpiRbMx) study and the National Health and Nutrition Survey 2018-2019 (ENSANUT 2018-2019, for its acronym in Spanish). The association of DF and PF with VDD or VDI was estimated using ENSANUT 2018-2019, and the association of DF and PF with SRb using EpiRbMx. All were estimated using logistic regression, with comparable samples selected from ENSANUT 2018-2019 and EpiRbMx. RESULTS: Altitude, latitude and obesity predicted VDI and VDD in ENSANUT women. In EpiRbMx, residence in a rural location during pregnancy increased the risk of SRb. For children, rural residence and latitude increased the risk of SRb, while the number of days exposed to the spring-summer season during months 6 to 11.9 of life was protective. CONCLUSIONS: risk of VDI and VDD in women (ENSANUT 2018-2019) increased with altitude, urban dwelling, overweight and obesity. The child and mother's place of residence, including altitude, latitude and rural classification were important predictors of SRb in EpiRbMx.

Abstract Objective: To describe the prevalence of deficiency (VDD) and insufficiency (VDI) of vitamin D (VD), by sociodemographic factors, obesity and physical activity in a probabilistic sample of Mexican women participating in Ensanut 2018-19. Materials and methods: In 1 262 women aged 20 to 49 years, the prevalence of VDD/IVD was estimated and the factors associated with it were evaluated with a multinomial regression model. Results: The prevalence of VDI was 46.1% and of VDD was 31.6%. The probability of presenting VDI and VDD was higher for residents of urban areas, in tertiles 2 and 3 of socioeconomic status, and with obesity, while was lower in women with moderate physical activity. Conclusión: The prevalence of vitamin D in Mexican women continues to be a public health problem in Mexico despite the high availability of sunlight in the country. It is necessary to promote healthy sun exposure in the population and consider fortifying foods with vitamin D.
Resumen Objetivo: Describir la prevalencia de deficiencia (VDD) e insuficiencia (VDI) de vitamina D (VD) por factores sociodemográficos, obesidad y actividad física, en una muestra probabilística de mujeres mexicanas participantes de la Encuesta Nacional de Salud y Nutrición 2018-19. Material y métodos: En 1 262 mujeres se estimó la prevalencia de VDD y VDI y se evaluaron los factores asociados con ellas con un modelo de regresión multinomial. Resultados: La prevalencia de VDI fue de 46.1% y de VDD fue 31.6%. La probabilidad de presentar VDI y VDD fue mayor en residentes de áreas urbanas, en terciles más altos de nivel socioeconómico y con obesidad, mientras que fue menor en mujeres con actividad física moderada. Conclusión: La prevalencia de VDI y VDD en mujeres mexicanas continúa siendo un problema de salud pública en México a pesar de la alta disponibilidad de luz solar en el país. Es necesario fomentar en la población una saludable exposición solar y considerar la fortificación de alimentos con vitamina D.

BACKGROUND: Food timing affects circadian rhythms involved in weight control. Regular consumption of breakfast may affect body weight. OBJECTIVE: We examined the relation between breakfast frequency with weight change in middle-age women over a 3-y period. METHODS: We used data from 65,099 nonpregnant women aged >20 y participating in the Mexican Teachers' Cohort (MTC) who at baseline (2006-2008) were cancer free and for whom self-reported breakfast frequency at baseline was available. We analyzed body weight change between baseline and the first follow-up (2011) according to breakfast frequency. Participants were classified according to baseline breakfast frequency 0, 1-3, 4-6, or 7 d/wk and meal frequency 1-2, 3-4, or ≥5 meals/d. We used linear and modified Poisson regression to analyze body weight change as a continuous variable and for weight gain ≥5 kg (yes/no), respectively. Models were adjusted for sociodemographic and lifestyle confounders. RESULTS: At baseline, 25% of participants were daily breakfast consumers and 18.4% of women increased ≥5 kg between 2008 and 2011. The prevalence of weight gain ≥5 kg among daily breakfast consumers was 7% lower than among those who skipped breakfast (prevalence ratio: 0.93; 95% CI: 0.89, 0.97; P-trend = 0.02). The association was stronger among normal-weight women at baseline with a corresponding estimate of 0.87 (95% CI: 0.79, 0.97; P-trend = 0.02). CONCLUSION: Daily breakfast consumption was inversely associated with weight gain ≥5 kg over 3 y in middle-aged Mexican women. Regular breakfast may be an important dietary factor for body weight change.

BACKGROUND: Polyunsaturated fatty acids (PUFAs) are essential to child growth and development. OBJECTIVE: To assess the effect of PUFAs-fortified infant formula on lipid profile, growth and micronutrient status in children 12 to 30 months old. METHODS: This study is a double-blind randomized controlled clinical trial. Two study groups were assessed: (a) milk-based infant formula with micronutrients and PUFAs (PUFAs) and (b) milk-based infant formula with micronutrients, no PUFAs added (Non-PUFAs). Children received prepared formula (240 mL) twice a day, according to the color-code assigned to each infant. Anthropometric measurements and venous blood samples were taken at each day-care center at baseline, and again after four months. Total serum lipid extraction was 0.5 mL. Samples were treated and modified by the Folch method and analyzed with gas chromatography. RESULTS: Changes in serum lipid profile (expressed as % FA) between baseline and four months showed a statistically significant increase in docosahexaenoic acid (DHA) (0.22 vs. -0.07, p < 0.05) and Alpha-Linoleic acid (0.08 vs. 0.02, p < 0.05) in infants who consumed PUFAs-fortified formula compared to Non-PUFAs-fortified formula. Infants increased their length/height-for-age Z-score: median change for the PUFAs group was 0.16 (95% CI = 0.08, 0.28) and 0.23 (95% CI = 0.14, 0.33) for Non-PUFAs, with no differences between groups. Median folate level was significantly higher among the PUFAs group compared to Non-PUFAs: -0.87 (95% CI = -1.38, -0.44) and -3.83 (95% CI = -4.65, -3.03) respectively. Consumption of both supplements was adequate and stable during the intervention. CONCLUSION: A significant improvement was observed in the lipid profile of children who received the PUFAs-fortified milk-based formula.

OBJECTIVE: Evaluate association of dietary patterns with metabolic syndrome (MetS) and metabolic markers. MATERIALS AND METHODS: 654 adolescents from Guadalajara, Jalisco, participated in a cross-sectional study. Diet was evaluated using a food frequency questionnaire; 24 food groups were integrated, and dietary patterns were derived using cluster analysis. MetS was defined according to International Diabetes Federation (IDF), Cook and colleagues, Ford and colleagues, and de Ferranti and colleagues criteria. RESULTS: Dietary patterns identified were: "DP1", "DP2", and "DP3". Among males, "DP3" was associated with MetS (Cook and collaborators) (OR, 12.14; 95%CI, 1.66-89.05), hypertriglyceridemia (OR, 3.89; 95%CI, 1.01-15.07), and insulin resistance (OR, 6.66; 95%CI, 1.12-39.70). "DP2" was associated with abdominal obesity (OR, 5.11; 95%CI, 1.57-16.66). CONCLUSIONS: "DP3" entertained a greater risk of MetS, hypertriglyceridemia, and insulin resistance, while "DP2" possessed a greater risk of abdominal obesity among adolescent males.

1) Background: Elevated hepcidin levels have been linked to anemia of inflammation (AI). Retinol deficiency has shown to upregulate hepcidin expression in animals, while conflicting evidence links VD status with hepcidin concentration in humans. The purpose of the study is to explore if VA and VD status are associated with hepcidin concentrations in older Mexican adults (OA). 2) Methods: A cross-sectional study was conducted in summer 2015, using serum samples from 783 fasting OA ages 60 and above residents from Campeche and Yucatán. VA deficiency (VAD) was defined as serum retinol concentration <20 µg/dL and VD deficiency (VDD) as 25(OH)D <50 nmol/L. The log-hepcidin was the outcome variable expressed as continuous and tertiles of its distribution. Linear and ordinal regression models were used. 3) Results: VAD was present in 3.4% and VDD in 9.5% of OA. Log-retinol was inversely associated with log-hepcidin (coeff.: -0.15, 95%CI: -0.2, -0.09). VAD status shown a higher probability than non-VAD for higher hepcidin tertiles (OR = 2.15, 95%CI: 1.24, 3.74). VDD states was not associated with hepcidin in the linear (coeff.: 0.16, 95%CI: -0.02, 0.34) nor the ordinal model (OR = 0.74, 95%CI: 0.42, 1.28). 4) Conclusions: VAD, but not VDD, status was inversely associated with hepcidin concentrations in OA.

Based on a nationally representative sample of young Mexican women aged 20 to 49 years (n = 3260), we sought to explore whether cardiovascular risk factors and acute myocardial infarction (AMI) were associated with vitamin D deficiency (VDD, defined as 25-OH-D <50 nmol/L). To this end, we obtained sociodemographic, serum and anthropometric data from the 2012 National Health and Nutrition Survey (ENSANUT 2012). Analyses were developed through logistic regression models adjusted for potential confounders. The prevalence of VDD was significantly higher in obese women (42.5%, 95% CI; 37.3-47.9) compared to women with a normal body mass index (29.9%, 95% CI; 23.5-37.1, p = 0.05), in those with high total cholesterol (TC) (45.6% 95% CI; 39.4-51.9) compared to those with normal TC levels (33.9%, 95% CI 30-38.1, p = 0.03), and in those with insulin resistance (IR) (44%, 95% CI; 36.9-51.7) or type 2 diabetes mellitus (T2DM) (58.6%, 95% CI 46.9-69.4) compared to those with normal glycemia (no insulin resistance: 34.7%, 95% CI; 30.9-38.8, p = 0.04 and no T2DM: 34.9%, 95% CI 31.4-38.6, p < 0.001). Utilizing individual models to estimate cardiovascular risk according to VDD, we found that the odds of being obese (odds ratio, OR: 1.53, 95% CI 1.02-2.32, p = 0.05), or having high TC levels (OR: 1.43, 95% CI; 1.05-2.01, p = 0.03), T2DM (OR: 2.64, 95% CI; 1.65-4.03, p < 0.001), or IR (OR: 1.48, 95% CI 1.04-2.10, p = 0.026) were significantly higher in women with VDD (p < 0.05). Odds were not statistically significant for overweight, high blood pressure, sedentarism, AMI, high serum concentration of triglycerides, homocysteine, or C-reactive protein models. In conclusion, our results indicate that young Mexican women with VDD show a higher prevalence of cardiovascular risk factors.

OBJECTIVE: to estimate energy, nutrient intake and diet adequacy in preschool-aged children based on data from the Mexican National Health and Nutrition Survey 2012. MATERIAL AND METHODS: dietary data in children < 5 years (n = 1,212) collected through a Semi-quantitative Food Frequency Questionnaire (SFFQ) were analyzed. Energy and daily nutrient intakes and adequacies were calculated comparing by sociodemographic characteristics. RESULTS: median daily energy intake was 1,252 kcal (adequacy 104%). Adequacies above 100% were observed for calcium, zinc, vitamin C, folate, vitamin B12, vitamin A and median of saturated fat. Low percent adequacies were observed for fiber, iron, polyunsaturated fat and vitamin D. Intakes were lower in the southern region compared to other regions. Most intakes and adequacies were higher in urban compared to rural areas, but fiber had the opposite trend. Indigenous children had low intakes and percent adequacies. CONCLUSIONS: risks of dietary deficiencies and excess are present in Mexican preschool-aged children, with marked differences across sociodemographicstrata.

Objetivo: estimar la ingesta de energía, nutrimentos y adecuación de la dieta de preescolares mexicanos de la Encuesta Nacional de Salud y Nutrición 2012. Material y métodos: se recogieron los datos dietéticos de niños < 5 años (n = 1.212) a través de un cuestionario semicuantitativo de frecuencia de consumo de alimentos (CSFCA). El consumo y la adecuación de energía y nutrimentos fueron calculados según las características sociodemográficas. Resultados: la mediana de ingesta de energía fue de 1.252 kcal (adecuación 104%). Se hallaron adecuaciones mayores al 100% para calcio, zinc, vitamina C, folato, vitamina B12, vitamina A y mediana de grasa saturada. Se observaron adecuaciones bajas para fibra, hierro, grasa poliinsaturada y vitamina D, e ingesta menor para la región sur comparada con otras regiones. Las ingestas y adecuaciones fueron más altas en área urbana en comparación con el área rural, excepto para fibra. Los niños indígenas presentaron ingestas y adecuaciones bajas. Conclusiones: la dieta de niños preescolares mexicanos presenta riesgo de deficiencias y excesos, con marcadas diferencias entre estratos Sociodemográficos

OBJECTIVE: To estimate energy and nutrient intakes and adequacies in Mexican adolescents. MATERIALS AND METHODS: Dietary intake was assessed in 1 961 adolescents who participated in the National Health and Nutrition Survey 2012 (Ensanut 2012), by a food frequency questionnaire. Medians of intakes and adequacies were estimated for energy, macroand micronutrients and are presented by residence area, region and household wealth index (HWI). Consumption by food groups was estimated. RESULTS: Median daily energy intake was 2 000 Kcal in males and 1 800 Kcal in females. High prevalences of inadequacy were observed for fiber, PUFAs, iron, zinc and calcium. These inadequacies were higher among individuals of low HWI. Moreover, excessive intakes of total and saturated fat were higher among adolescents of higher HWI. CONCLUSIONS: The diet of Mexican adolescents is deficient in essential nutrients for good health and high in saturated fat. Actions are needed to promote a healthy diet.
