Proinflammatory dietary pattern and depression risk in older adults: Prospective analyses from the Seniors-ENRICA studies.

BACKGROUND & AIMS: Only a few studies have assessed the association between a proinflammatory diet and the risk of depression in older adults, and they have rendered weak results. The present study analysed the association between the Dietary Inflammatory Index (DII) and incident self-reported diagnosis or symptoms of depression in two cohorts of community-dwelling older adults in Spain. METHODS: We used data from the Seniors-ENRICA-I (SE-I) and Seniors-ENRICA-II (SE-II) cohorts. In both cohorts, the baseline DII was calculated from habitual food consumption estimated with a validated computer-based diet history. The incidence of both physician self-reported diagnosis of depression and mild-to-major depressive symptoms (≥3 on the 10-item Geriatric Depression Scale) was analysed. Logistic regression models were adjusted for the main potential confounders, such as sociodemographics, lifestyles, and comorbidities. The results of both cohorts were pooled using a random effects model. RESULTS: Among the 1627 participants in SE-I (mean age 71.5 ± 5.5 y, 53.1% women) and the 1579 in SE-II (mean age 71.4 ± 4.2, 46.7% women), 86 (5.3%) and 140 (8.9%) incident cases of depression were identified after a mean 3.2-y and 2.3-y follow-up, respectively. The fully adjusted odds ratio (95% confidence interval) of incident depression for the highest (the highest proinflammatory diet) versus the lowest quartile of DII was 2.76 (1.25-6.08, p-for-trend = 0.005) in the SE-I, 1.90 (1.04-3.40, p-for-trend = 0.005) in the SE-II and 2.07 (1.01-3.13) in the pooled cohorts. The results were consistent across strata defined by sex, age, physical activity, loneliness/poor social network, and morbidity. CONCLUSIONS: A proinflammatory dietary pattern is associated with depression risk in older adults. Future research should evaluate whether reducing the inflammatory component of diet leads to reduced depression symptoms in this population.

Concerning “The HEARTS app: a clinical tool for cardiovascular risk and hypertension management in primary health care”

Dear editor, We read with interest the article entitled “The HEARTS app: a clinical tool for cardiovascular risk and hypertension management in primary health care” by Ordunez and colleagues, published on March 28th, 2022 (1). This article describes a recently developed app to assess cardiovascular disease (CVD) risk, as well as its use, potential functionality, and validation process. Despite the central role of the HEARTS initiative in the Americas and in the vulnerable region of Latin America and the Caribbean (LAC), we believe that the interpretation of the findings of this study requires some caution. There are some methodological issues in this manuscript that could compromise the strong conclusion that “the HEARTS app is an essential step in the journey towards eliminating preventable CVD in the Americas.” First, the risk prediction models that inform this app are derived from 85 cohorts from high-income countries in the Emerging Risk Factors Collaboration study (2). Of these, we were only able to identify the Puerto Rico Heart Health Program study as directly representative of the LAC region. Therefore, the lack of representativeness of the models for risk-prediction should be made more explicit. At the same time, the important role of the STEPwise approach to surveillance to obtain population-level indicators and trends, as well as calibration of the risk-prediction models should be both considered as potential solutions to this issue. Second, the authors state that “the app is intended to be used in clinical practice, especially at the primary health care level” although it can also “be used by anyone in the general population.” If the use of the app is available to the general public, this could systematically exclude underrepresented groups by creating differential engagement and generating digital inequity (3). Hence, the “ideal” target population of the app in low- and middle-income countries should be specified. Third, the language of the article should reflect the uncertainty regarding the long-term success of this digital health application in the region, which will likely depend on how it is implemented and maintained over time, and the promptness of the initiation of effective pharmacological treatment after the obtention of a risk score. Several barriers to the implementation of CVD risk calculators in primary care have been described, including time constraints, lack of electronic health records integration, and patient fears (4). Low-resource contexts potentially require tailoring of the app to address some of these barriers and ensure sustainability. The burden of CVD in LAC, estimated at 3 497.14 disabilityadjusted life years per 100 000 (range, 3 226.2 – 3 790.1), appears to be highly influenced by the years lived with disability due to ischemic heart disease (5) and by the increasing impact of high systolic blood-pressure (≥110-115 mmHg according to the Global Burden of Disease definition) as the leading mortality risk factor in the region. This public health scenario presents both a tremendous challenge and an opportunity for improvement. The HEARTS app is a promising driver of change. However, its validity should be evaluated in view of some methodological caveats and its implementation capacity should stress the letter “A” of its acronym to advocate for equitable “access to essential medicines and technology” in places where the availability and affordability of generic drugs is still scarce.

Combined Impact of Traditional and Nontraditional Healthy Behaviors on Frailty and Disability: A Prospective Cohort Study of Older Adults.

OBJECTIVES: To assess the short- and long-term association of 6 healthy behaviors (not smoking, vigorous to moderate physical activity, healthy diet, adequate sleeping duration, not being sedentary, and daily social interaction) with incident frailty and disability. DESIGN: Prospective population-based study. SETTINGS AND PARTICIPANTS: In 2001, 4008 community-dwelling individuals aged ≥60 years in Spain were recruited. Participants were followed up until 2003, when a short-term phone interview of the remaining 3235 individuals was performed. Then, the participants were followed up until 2009, when a long-term phone interview was conducted with 1309 participants. MEASURES: At baseline, a home interview and a physical examination were conducted to assess healthy behaviors. At baseline and at follow-ups, we ascertained frailty and 4 domains of disability: limitation in instrumental activities of daily living, restriction in daily activities, limitation in mobility, and self-care limitation. RESULTS: In the short-term analyses, vigorous to moderate physical activity and not being sedentary were associated with a reduction in frailty, multivariable odds ratios (OR) (95% confidence interval) 0.55 (0.35-0.85) and 0.43 (0.26-0.72). Vigorous to moderate physical activity and adequate sleeping duration decreased instrumental activities of daily living limitation OR 0.63 (0.44-0.91) and 0.69 (0.53-0.89) as well as self-care limitation OR 0.62 (0.41-0.92) and 0.65 (0.45-0.94). Adequate sleep duration and not being sedentary decreased restriction in daily activities OR 0.67 (0.49-0.90) and 0.57 (0.36-0.91). Vigorous to moderate physical activity and healthy diet decreased limitation in mobility OR 0.58 (0.35-0.96) and 0.73 (0.54-0.97). Considering these 5 healthy behaviors, participants who scored 5 (vs ≤ 2) in the combined score had a lower risk of frailty and disability. In the long-term analyses, results showed the same direction as in short-term analyses. CONCLUSIONS AND IMPLICATIONS: The combination of healthy behaviors is associated with a substantial reduction in the risk of frailty and of most disability outcomes in older adults.

Low vitamin intake is associated with risk of frailty in older adults.

Background: the association between vitamin intake and frailty has hardly been studied. The objective was to assess the association of dietary vitamin intake with incident frailty in older adults from Spain. Methods: data came from a cohort of 1,643 community-dwelling individuals aged ≥65, recruited in 2008-10 and followed up prospectively throughout 2012. At baseline, 10 vitamins were assessed (vitamin A, thiamine, riboflavin, niacin, vitamins B6, B12, C, D, E and folates) using a validated face-to-face diet history. Incident frailty was identified using Fried's definition as having ≥3 of the following five criteria: unintentional weight loss of ≥4.5 kg, exhaustion, weakness, slow walking speed and low physical activity. Nonadherence to the recommended dietary allowances (RDA) was considered when the intake of a vitamin was below the recommendation. Analyses were performed with logistic regression and adjusted for main confounders. Results: during a 3.5-year follow-up, 89 (5.4%) participants developed frailty. The odds ratios (95% confidence interval) of frailty for those in the lowest versus the highest tertile of vitamin intake were 2.80 (1.38-5.67), P-trend: 0.004, for vitamin B6; 1.65 (0.93-2.95), P-trend: 0.007, for vitamin C; 1.93 (0.99-3.83), P-trend: 0.06, for vitamin E and 2.34 (1.21-4.52), P-trend: 0.01, for folates. Nonadherence to the RDAs of vitamins was related to frailty for thiamine odds ratio (OR): 2.09 (1.03-4.23); niacin OR: 2.80 (1.46-5.38) and vitamin B6; 2.23 (1.30-3.83). When considering tertiles of RDAs for the 10 vitamins those who met <5 RDAs had a higher risk of frailty, OR: 2.84 (1.34-6.03); P-trend: <0.001, compared to those who met >7. Conclusion: a lower intake of vitamins B6, C, E and folates was associated with a higher risk of frailty. Not meeting RDAs for vitamins was also strongly associated.

Chocolate and health-related quality of life: a prospective study.

BACKGROUND: Chocolate consumption has been associated with a short-term reduction in blood pressure and cholesterol, and improvement of insulin sensitivity; however, participants could not be aware of presenting hypertension or hypercholesterolemia. Moreover, the effect of chocolate on mental health is uncertain. This study assessed the association of regular chocolate consumption with the physical (PCS) and mental (MCS) components of health-related quality of life (HRQL). MATERIALS AND METHODS: We analyzed data from a cohort of 4599 individuals recruited in 2008-2010 and followed-up once prospectively to January 2013 (follow-up mean: 3.5 years). Regular chocolate consumption was assessed at baseline with a validated diet history. HRQL was assessed with the SF-12 v.2 at baseline and at follow-up. Analyses were performed with linear regression and adjusted for the main confounders, including HRQL at baseline. RESULTS: At baseline, 72% of the study participants did not consume chocolate, 11% consumed ≤10 g/day and 17% >10 g/day. Chocolate consumption at baseline did not show an association with PCS and MCS of the SF-12 measured three years later. Compared to those who did not consume chocolate, the PCS scores were similar in those who consumed ≤10 g/day (beta: -0.07; 95% confidence interval (95% CI): -0.94 to 0.80) and in those who consumed >10 g/day (beta: 0.02; 95% CI:-0.71 to 0.75); corresponding figures for the MCS were 0.29; 95% CI: -0.67 to 1.26, and -0.57; 95%CI: -1.37 to 0.23. Similar results were found for sex, regardless of obesity, hypertension, hypercholesterolemia, diabetes or depression. CONCLUSIONS: No evidence was found of an association between chocolate intake and the physical or mental components of HRQL.

The burden of blood-pressure-related cardiovascular mortality in Mexico.

This study shows that in Mexico, a country at an advanced stage in the epidemiologic transition, with the national burden of disease dominated by noncommunicable diseases, elevated blood pressure is a major clinical and public health problem. 31.7% of the Mexican individuals aged 50 and over had systolic hypertension, and 47.3% were at systolic prehypertensive levels. Also, approximately half of all cardiovascular deaths that occurred annually in the population of Mexico aged ≥50 years are attributable to above optimal levels of systolic blood pressure. We think these estimates may help order health priorities in Mexico (and other middle-income countries) at a time when the costs of medical care take a considerable share of the gross national product in most countries.

Sleep quality and the metabolic syndrome: the role of sleep duration and lifestyle.

BACKGROUND: This study examined the association between sleep quality and the metabolic syndrome and whether if it is independent of sleep duration and if it can be explained by lifestyles linked to sleep quality. METHODS: Cross-sectional study conducted from 2008 to 2010 with 10 342 individuals representative of the population aged ≥18 years in Spain. Poor sleep quality was ascertained through self-reported difficulty falling asleep, difficulty maintaining sleep and sleeping pill consumption. Metabolic syndrome was defined according to the recent harmonized definition. Analyses were conducted with logistic regression and adjusted for the main confounders. RESULTS: Difficulty falling asleep was associated with higher frequency of metabolic syndrome after adjustment for sociodemographic variables, lifestyle and diagnosed morbidity [odds ratio (OR) = 1.25; 95% confidence interval (CI) = 1.06-1.47]. The association was slightly attenuated after further adjusting for sleep duration (OR = 1.23; 95% CI = 1.04-1.46) and held after additional adjustment for energy intake, adherence to a Mediterranean dietary pattern, energy spent in physical activity and time watching TV (OR = 1.20; 95% CI = 1.01-1.42). No associations were found between metabolic syndrome and other sleep quality indicators. Difficulty falling asleep was associated with high blood pressure in the fully adjusted analyses (OR = 1.17; 95% CI = 1.00-1.37) but not with the rest of components of metabolic syndrome. CONCLUSIONS: Difficulty falling asleep is associated with metabolic syndrome and, in particular, with high blood pressure. This association is independent of sleep duration and is not due to lifestyles related to poor sleep. This finding should be replicated in prospective studies using objective sleep measures; also, the influence of antihypertensive and lipid-lowering drug treatment on this association should be further studied.

Blood pressure responses in young adults first exposed to high altitude for 12 months at 3550 m.

To determine the changes in blood pressure (BP) and related variables in sea-level young adults with chronic exposure to high altitude, a longitudinal study was performed in male army recruits (n = 346; age 17.9 +/- 0.1 yr; BMI, 22.5 +/- 0.3 kg/m(2)) first exposed to 3550-m altitude for 12 months. Fifty male recruits (age 17.8 +/- 0.6 and BMI 22.6 +/- 0.3 kg/m(2)) never exposed to altitude were used as controls. A sustained higher mean diastolic BP (DBP) (82.1 +/- 1.0 mmHg at month 3; 81.3 +/- 0.9 mmHg at month 12) was observed, compared to first exposure and the control group (p < 0.001). The BP values were always higher than those of the sea-level control group (systolic blood pressure (SBP) 109 +/- 2.3 and DBP 67.4 +/- 0.8; p < 0.001), and a large proportion of subjects steadily presented overoptimal values for either systolic BP (SBP) (64%) or DBP (77%) and hypertensive DBP values (40%). The higher DBP was associated with lower Sao(2) (OR = 0.919; p < 0.05). In addition, the acute mountain sickness (AMS) score showed a slight decrease during re-exposure (3.9 +/- 0.3 vs.3.4 +/- 0.3; p < 0.001) and an inverse association to the before-descending Sao(2) at month 3 (OR = 0.906, p < 0.01). These data suggest that BP stabilization can take longer than currently thought and that each parameter has a different profile of change. Further, a sustained high DBP should be a matter of epidemiological concern and emphasizes the need for BP monitoring among young lowlanders exposed to high altitude.

[Factors associated the control of hypertension among older Spaniards, over 60 years of age]. / Factores asociados al control de la hipertension arterial en personas mayores de 60 años en España.

BACKGROUND: In the last decade, improvement has been observed in the control of arterial hypertension in Spain. Such control has an effect in the decrease of cardiovascular morbidity and mortality. The objective of the study was to identify factors associated to the control of arterial hypertension in awareness of hypertension among males and females who receive pharmacological treatment. METHODS: A cross-sectional analysis, made in basis of the following study data: "Arterial Hypertension and other risk factors in the population of 60 years old and more in Spain". The sample included 1461 hypertensive patients treated pharmacologically, selected by probabilistic and multistage sampling. The information recollected about the control of arterial hypertension, social and demographic variables, lifestyle, healthcare service usage, and life quality related to health, by residence interviewing. RESULTS: No differences between gender were observed in the control of hypertension (p = 0.09), In men control were significantly linked to: residence in rural areas (OR = 1.83; CI at 95%: 1.06-3.14); being single (OR = 3.40; CI at 95%: 1.32-8.74); and exercising (OR = 1.69; CI at 95%: 1.06-2.69). Women who consume alcohol in a moderate way controlled themselves more (OR = 1.63; CI at 95% 1.14-2.33). CONCLUSIONS: This research determines, according to gender, some factors related with the control of arterial hypertension in awareness of hypertension patients treated pharmacologically. In male patients the control is related to: living in rural areas, being single and physical activity. While in females control was associated with moderate alcohol consumption.

[Determinants of the adherence to therapeutic plan in elderly Spaniards, over 60 years of age]. / Determinantes del cumplimiento terapéutico en personas mayores de 60 años en España.

OBJECTIVE: To identify factors associated with the adherence to a therapeutic plan of awareness of hypertension. MATERIAL AND METHODS: The data of the study "Arterial hypertension and other factors of risk in the elderly (> or = 60 years) Spanish population". This was a population-based survey of 4.009 older Spaniards. Information for this survey was obtained thorough household personal interviews to evaluate if these determining factors are independent of socio-demographic variables, the use of health system, lifestyles and the quality of life related to health. RESULTS: In men, the adherence to a therapeutic plan according to the regions studied (OR Rural = 3.9; OR Cantabrian = 1.9). Beside general health (OR = 1.01). With respect to the women, the ones that complied with the therapeutic plan more frequently had a low scholastic level (OR = 1.8), physical condition (OR = 1.02), and had more frequent home medical visits monthly (OR = 3.0). The women with poor adherence had two chronic illnesses (OR = 0.6) CONCLUSIONS: There are regional differences, gender, educational and to measure health-related quality of life. This demonstrates poor adherence, so the strategy should be directed toward in this variables mentioned.

An international comparative study of blood pressure in populations of European vs. African descent.

BACKGROUND: The consistent finding of higher prevalence of hypertension in US blacks compared to whites has led to speculation that African-origin populations are particularly susceptible to this condition. Large surveys now provide new information on this issue. METHODS: Using a standardized analysis strategy we examined prevalence estimates for 8 white and 3 black populations (N = 85,000 participants). RESULTS: The range in hypertension prevalence was from 27 to 55% for whites and 14 to 44% for blacks. CONCLUSIONS: These data demonstrate that not only is there a wide variation in hypertension prevalence among both racial groups, the rates among blacks are not unusually high when viewed internationally. These data suggest that the impact of environmental factors among both populations may have been under-appreciated.

[The obesity epidemic and related factors: the case of Spain]. / La epidemia de obesidad y sus factores relacionados: el caso de España.

The obesity epidemic is a global phenomenon that does not respect geographic or socio-demographic boundaries. Thus, research on factors related to the obesity epidemic has focused on social and economic characteristics of modern societies. This article discusses obesity in Spain and trends in several associated factors. Together with the increase in the prevalence of obesity, important changes in the population's dietary pattern have been observed, although total energy and fat intake appear to be stable. According to several indirect indicators, sedentary behavior predominates, although the percentage of the population reporting some leisure exercise is increasing. An increase in the amount of leisure time in modern societies is suggested as an explanation for this paradox. Factors related to energy expenditure could be as important as dietary factors in the genesis of the obesity epidemic.

La epidemia de obesidad y sus factores relacionados: el caso de España / The obesity epidemic and related factors: the case of Spain

La epidemia de obesidad es un fenómeno universal que no parece reconocer límites ni geográficos ni sociodemográficos. Las investigaciones sobre los factores responsables de la epidemia se centran sobre algunas de las condiciones sociales y económicas que imperan en las sociedades actuales. El presente artículo muestra la situación de la obesidad en España y la tendencia de una serie de factores potencialmente relacionados. El incremento en la prevalencia de obesidad se acompañó de importantes cambios en el patrón de alimentación de la población a pesar de una tendencia estabilizada en la ingesta calórica total y de grasas. Diversos indicadores indirectos muestran la tendencia sedentaria de la población, a pesar de que un mayor porcentaje de la población declara realizar ejercicio físico en su tiempo libre. Los factores dependientes del gasto energético parecen tan o más importantes que los derivados del ingreso. Para explicar la situación paradójica de los distintos indicadores de sedentarismo se sugiere la hipótesis de un aumento del "stock de tiempo libre" en las sociedades actuales
