The dietary inflammatory index (DII) is a new tool to assess the inflammatory potential of the diet. In the present study, we aimed to determine the association between the DII and BMI, waist circumference and waist:height ratio (WHtR). We conducted a cross-sectional study of 7236 participants recruited into the PREvención con DIeta MEDiterránea trial. Information from a validated 137-item FFQ was used to calculate energy, food and nutrient intakes. A fourteen-item dietary screener was used to assess adherence to the Mediterranean diet (MeDiet). Sex-specific multivariable linear regression models were fitted to estimate differences (and 95 % CI) in BMI, waist circumference and WHtR across the quintiles of the DII. All nutrient intakes, healthy foods and adherence to the MeDiet were higher in the quintile with the lowest DII score (more anti-inflammatory values) except for intakes of animal protein, saturated fat and monounsaturated fat. Although an inverse association between the DII and total energy was apparent, the DII was associated with higher average BMI, waist circumference and WHtR after adjusting for known risk factors. The adjusted difference in the WHtR for women and men between the highest and lowest quintiles of the DII was 1·60 % (95 % CI 0·87, 2·33) and 1·04 % (95 % CI 0·35, 1·74), respectively. Pro-inflammatory scores remained associated with obesity after controlling for the effect that adherence to a MeDiet had on inflammation. In conclusion, the present study shows a direct association between the DII and indices of obesity, and supports the hypothesis that diet may have a role in the development of obesity through inflammatory modulation mechanisms. ; The PREDIMED trial was supported by the official funding agency for Biomedical Research of the Spanish Government, Instituto de Salud Carlos III (ISCIII), through grants provided to research networks specifically developed for the trial: RTIC G03/140 (Coordinator: R Estruch, MD, PhD), CIBERobn, and RTIC RD 06/0045 (Coordinator: MA Martínez-González, MD, PhD).

Introduction: Physical fitness is a fundamental capability required of military personnel, but studies focusing on longitudinal changes in physical fitness and anthropometrics in soldiers are lacking. The aim was to evaluate physical fitness and anthropometrics in soldiers during their early career. Methods: A 3-year prospective study included 180 male soldiers (baseline age 26±2 years) with measures of a 12 min running test, standing long jump, sit-up and push-up tests, and body mass, height and waist circumference (WC). Baseline data were stratified into tertiles, and the changes within each tertile were analysed using dependent t-tests and analysis of variance. Results: 12 min running test distance decreased on average by 2% (−54 m), sit-up performance 3% (−1.5 repetitions (reps)/min), push-up performance 4% (−1.9 reps/min) and standing long jump performance 1% (−2.1 cm) over the 3-year period (p<0.05). Both aerobic and muscular fitness decreased consistently among the highest baseline tertile (12 min running test: −70 m, sit-ups: −3.2 reps/min, push-ups: −7.5 reps/min, standing long jump: −5.5 cm; p<0.001), whereas both aerobic and muscular fitness levels were maintained and push-up performance was improved (p<0.05) in the lowest baseline tertiles. Body mass increased on average by 4% (+3.4 kg) and WC by 4% (+3.9 cm) (p<0.001), and these increases were observed for all baseline tertiles (p<0.05). Conclusions: Small decrements in physical fitness and anthropometrics exist during the early career of soldiers. The changes in physical fitness differed according to baseline fitness levels. The results indicate that support for exercise training may be needed even in a soldier's early career. ; peerReviewed

Introduction: Military training programmes are often similar for male and female recruits despite sex differences in physical performance that may influence training adaptations during military service. The present study aimed to compare changes in physical fitness and anthropometrics between Finnish female and male recruits during military service. Methods: A total of 234 690 male and 3549 female recruits participated in fitness tests at the beginning and end of military service between 2005 and 2015. Anthropometric measurements were body mass, height, body mass index (BMI) and waist circumference (WC). Fitness tests consisted 12 min running, standing long jump, and sit-ups and push-ups. Results: No changes were observed in anthropometrics, while both sexes improved most of the fitness test results. After adjustment for service time, branch, age, initial fitness test results, BMI and WC, improvement in running test performance was 158 m (95% CI 142 to 173, p≤0.001) greater in male than female recruits. Similarly, improvements were larger in male recruits for push-ups (5 reps/min, 95% CI 5 to 6, p≤0.001), sit-ups (2 reps/min, 95% CI 2 to 3, p≤0.001) and standing long jump (12 cm, 95% CI 11 to 13, p≤0.001) when compared with women. Conclusions: The study revealed sex differences in adaptations to the standardised military training. Both male and female recruits improved their physical fitness, but smaller gains were observed in women using the same training programme. The mechanisms explaining sex differences in adaptations to military training, and whether tailored training programmes are needed specifically for female recruits to reduce sex differences during military service, warrants further studies. ; peerReviewed

Objective: to assess the long-term evolution of biological living standards in rural Catalonia and to compare it with the corresponding figures in urban areas. Methods: using data from military records of conscripts from six towns in western Catalonia, we construct an annual height series. Height is standardised at the age of 21 years. We also construct a body mass index (BMI) for conscripts born in 1891 and 1934-39. The annual height series for western Catalonia is systematically compared to the series for Reus, Catalonia's second largest city during the second half of the 19th century. Results: comparing the cohorts born in the periods 1840-49 and 1951-60, we find that height increased by 5.7 centimetres over this period. However, the increase was not distributed equally over time. In the second half of the 19th century, rural heights stagnated over the long run and declined relative to urban heights. In the cohorts born in the decades between 1910 and 1950, rural heights rose by more than 5 centimetres, and converged with those of Reus. Conclusion: we provide new evidence for the current debate on the rural-urban height gap. Between the 1840s and the 1950s, heights in rural western Catalonia grew at rates similar to those recorded in certain urban areas, but growth rates differed depending on the period of analysis. This study underlines the importance of adopting long-term perspectives, and stresses that rural-urban height differences tend to be time-and space-specific.

Introduction. The physical fitness of male conscripts has decreased, and body mass increased during the last few decades, especially in Nordic countries. However, limited research-based reports are available concerning the physical fitness profiles of female recruits. Therefore, the purpose of this study was to investigate changes in physical fitness and body composition of female recruits entering voluntary Finnish military service between the years 2005 and 2015. Materials and methods. Data were collected from the initial fitness tests performed in military units during the first two weeks of military service. A total of 3875 healthy female recruits (19.9±2.1 yr.) participated in the fitness tests. Fitness tests consisted 12-min running test and muscle fitness tests, which were sit-ups, push-ups and standing long jump. Results. Increases in mean body mass (4.2%, p≤0.01) and body mass index (3.8%, p<0.01) were observed between 2005 and 2015. In addition, the proportion of overweight and obese female recruits increased by 12% (p≤0.001). Mean endurance performance and overall muscle fitness remained unaltered during the study period, except for a decline in push-ups performance. However, the proportion of female recruits with poor endurance performance increased from 19.6% to 27.8% (p≤0.001) between 2005 and 2015. Body mass was inversely associated with 12-minute running test distance (r=-0.35, p≤0.001) and muscle fitness index (r=-0.25, p≤0.001). Conclusions. In conclusion, the present study revealed that an increasing proportion of female recruits are overweight and/or have poor endurance performance, which are known risk factors for musculoskeletal injuries and premature discharge from military service. Therefore, specialized training programs should be designed specifically for female recruits with lower levels of fitness prior to military service. ; peerReviewed

The present study aimed to compare the effects of swimming and walking after 24 weeks of training on anthropometric indicators of obesity, physical activity, coronary risk and health-related quality of life among military police officers of the state of Santa Catarina, Brazil. The sample included 51 military police officers (male) whose ages ranged from 22 to 49 years, with a mean age of 35.53 ± 7.63 years, and who fulfilled the inclusion criteria of the study, which was conducted between the months of June and December 2012. The subjects were interviewed to collect demographic and occupational data as well as anthropometry, physical activity level and health. The volunteers were divided into the following three groups according to their preference: swimming experimental group (n = 24), walking experimental group (n = 24), and control group (n = 24). Statistical analyses were performed using descriptive analysis, oneway and two-way ANOVAs followed by Bonferroni's post hoc test, Student's t-test, the Kruskal-Wallis test and the Mann-Whitney U test followed by Bonferroni's correction, the Wilcoxon test and Cohen's d test. After 24 weeks of training, the waist circumference, conicity index, waist-to-height ratio, physical activity at work, vigorous activities and coronary risk were significantly different in the swimming group, and the percentages of fat, lean mass and fat mass were significantly different in the walking group. The swimming exercise program contributed to significant reductions in waist circumference, conicity index, the waist-to-height ratio and coronary risk and to increased levels of physical activity at work and vigorous activities. In addition, the walking exercise program contributed to significant reductions in relative body fat and fat mass and increased lean mass among military police officers. ; O presente estudo teve como objetivo comparar os efeitos da natação e caminhada após 24 semanas de treinamento sobre os indicadores antropométricos de obesidade, atividade física, risco coronariano e com qualidade de vida relacionada á saúde entre os policiais militares do estado de Santa Catarina, Brasil.

Este ensayo presenta resultados de estimaciones de estaturas medias para diversas regiones de Argentina durante el período 1850-1950. Esta evidencia, tomada de registros de reclutas y prisioneros, es utilizada para cuestionar algunas de las generalizaciones sobre el crecimiento económico argentino, basadas en datos de ingresos per-cápita y salarios. Se sostiene que, en términos de estatus nutricional y de salud, la era del progreso liberal derramó menos bienestar que el esperado. Algo similar ocurrió con el crecimiento agro-exportador de principios del siglo XX. Por el contrario, el período conocido como la «gran demora» —el período de inter-guerras— fue testigo de notables aumentos de bienestar biológico, particularmente en la década de 1930. Se sugiere también que durante la segunda guerra mundial y los primeros gobiernos peronistas, las estimaciones sobre alturas indican un retraso nutricional y de salud en el conurbano bonaerense. El ensayo presenta además datos sobre la distribución regional de las alturas, que reflejan un alto grado de desigualdad regional hacia la década de 1920. ; This essay presents recent estimates of average heights for different regions of Argentina during the period 1850-1950. This evidence, taken from registers of prisoners and military recruits, serves to question some traditional views of Argentine economic growth based on income and wage data. The essay suggests that the era of liberal progress resulted in less welfare among the lower classes than is usually assumed. A similar situation occurred during the agrarian-export growth of the first decade of the 20th century. In contrast, the period known as the «great delay» witnessed notable improvements in biological welfare, particularly during the 1930s. In addition, height estimates indicate that during WWII and the first Peronist administrations there was a nutritional setback in the Buenos Aires industrial belt. Data on the provincial distribution of heights for the 1920s show an important degree of regional inequality.

[EN]: Introduction: the main objectives of weight-loss interventions are to decrease fat mass while maintaining fatfree mass. Objective: our aim was to address effectiveness body composition changes in overweight adolescents assessed by different body composition methods following an obesity intervention programme. Material and methods: the life-style intervention was multi-disciplinary, with 13 months follow-up. Participants were 13-to-16 year-old overweight, or obese, Spanish adolescents. The adolescents (n = 156; 54.8% females) had body composition measured with anthropometry, dual-energy X-ray absorptiometry and air-displacement plethysmography. All measurements were made at baseline, and after 2- and 13-months. Repeated measures analysis of covariance to compare mean anthropometric changes over time and the Bonferroni correction were applied. Imputation of anthropometric measures was performed. Results: a high significant decrease in fat mass index was achieved in males after 2-and 13-months of intervention as measured by anthropometry (1.16 and 1.56 kg / m2, respectively), X-ray absorptiometry (1.51 and 1.91 kg / m2) and plethysmography (2.13 and 2.44 kg/m2). Moreover, a short and long-term maintenance of fat-and fat-free mass index was observed by X-ray absorptiometry in females (0.94 and 0.68 kg/m2). Conclusion: our multidisciplinary approach to lifestyle intervention has a favourable impact on body fat mass and fat-free mass index as well as waist-to-height ratio, over 13 months intervention in overweight and obese adolescents. ; [ES]: Introducción: el principal objetivo de las intervenciones de pérdida de peso es disminuir la masa grasa manteniendo la masa libre de grasa.

[Abstract] Assessing physical fitness has emerged as a proxy of the health status of children and adolescents and therefore as relevant from a public health point of view. DAFIS is a project included in Plan Galicia Saudable (Healthy Galicia Plan) of the regional government of Galicia (Spain). DAFIS consists of an on-line software devoted to record the results of a standard physical fitness protocol carried out as a part of the physical education curriculum. The aims of this study were: to obtain normative values of physical fitness of the Galician school population evaluated in the DAFIS project, and to identify a reduced number of components and tests able to capture a significant amount of the variability in the physical fitness of children and adolescents. From an initial sample of 27784 records, 15287 cases (7543 males, 7744 females) were considered after filtering. Generalized Additive Models for Location, Scale and Shape were used for obtaining percentile curves and tables for each sex. Furthermore, a principal components analysis was performed, selecting the number of components by applying the Kaiser's rule and selecting a subset of variables considering the correlation between each variable and the components. Percentile curves and normative values are reported for each test and sex. Physical fitness was better in boys than in girls throughout age groups, except for flexibility that was consistently higher in girls. Two main components were detected throughout age groups: the first one representing body composition and partially cardiorespiratory fitness and the second one muscular fitness. For boys and girls, waist to height ratio had the highest correlations with the first component in four out of six age groups. The highest correlation with the second component, was most frequently observed for the handgrip test both in boys and girls (four out of six age groups). This study provides evidence about the utility of school community actions like DAFIS aimed to track the health-related fitness of children and adolescents. The results suggest that fat mass distribution (i.e., waist to height ratio and waist circumference) and muscular performance (mainly handgrip) concentrate a high proportion physical fitness variance.

Abstract Metabolic syndrome (MetS) is a cluster of obesity-related cardiometabolic risk factors. It predicts the development of cardiovascular disease and type 2 diabetes, which are major public health concerns. Visceral obesity and insulin resistance are the predominant underlying factors of MetS, other diagnostic components being elevated blood pressure, high triglycerides, and low HDL-cholesterol. The most important treatment of MetS is through lifestyle changes. There are limited data concerning the prevalence of MetS among young populations. Furthermore, even though the effects of physical activity on MetS components are well established at an individual basis and in some subpopulations, large population-based data about associations of young men's fitness and MetS-related cardiometabolic risk factor changes are warranted. In Finland, military service is compulsory for males. In 2005, 1,160 young men (mean age 19.2 years, range 18–28 years) were followed throughout their military service (6–12 months) in the Sodankylä Jaeger Brigade. The military service period includes high amounts of physical exercise, but no dietary restrictions. Physical fitness, anthropometrics, body composition, and cardiometabolic risk factors were assessed at the beginning and at the end of military service. Among the entire study population, the prevalence of MetS was 3.5–6.8 %, depending on the definition used, and increased in parallel with an increasing body mass index. On the average, the military training period resulted in a decrease in body weight and amount of fat tissue, especially visceral fat, and improved physical fitness. Body composition and fitness improvements were more pronounced in overweight and obese service men. Beneficial changes in body composition and related cardiovascular risk factor improvements were associated with increased physical fitness, especially aerobic fitness. This study indicates that an improvement in physical fitness is related to improvements in body fat distribution and cardiovascular health at population level in young men. This is an age when co-morbidities are usually as yet non-existing, but might be most efficiently prevented by lifestyle changes, such as becoming physically active. ; Tiivistelmä Metabolinen oireyhtymä on tyypin 2 diabeteksen ja valtimosairauksien riskitekijäryväs. Sen osatekijöitä vyötärölihavuuden lisäksi ovat kohonnut verenpaine, insuliiniresistenssi, korkea veren triglyseridipitoisuus ja HDL-kolesterolin pitoisuus. Viime vuosina metabolinen oireyhtymä on yleistynyt lihavuuden lisääntymisen myötä. Lihavuuden ja sen liitännäissairauksien tärkeimpiä hoitokeinoja ovat laihtumiseen tähtäävät elintapamuutokset. Liikunnan tiedetään johtavan edullisiin kehonkoostumusmuutoksiin sekä kardiovaskulaaririskitekijöiden parantumiseen. Laajat väestötason tutkimukset nuorten aikuisten kunnon ja varhaisten valtimosairausriskitekijöitten muutosten välisistä yhteyksistä kuitenkin puuttuvat. Varusmiespalvelus tarjoaa ainutlaatuisen mahdollisuuden tarkastella nuoria miehiä laajassa, lähes valikoitumattomassa väestöotoksessa, sillä Suomessa varusmiespalvelus on pakollinen kaikille miehille. Vuonna 2005 1160 miestä (keski-ikä 19,2 vuotta, vaihteluväli 18–28 vuotta) astui palvelukseen Sodankylän jääkäriprikaatissa. Kehonkoostumus, fyysinen kunto, antropometria sekä veren rasva-arvot mitattiin varusmiespalveluksen (6–12 kk) alussa ja lopussa. Metabolisen oireyhtymän vallitsevuus oli 3,5–6,8 % käytetystä määritelmästä riippuen. Se oli yleisempi korkeimmissa painoindeksiluokissa. Keskimäärin koko aineistossa varusmiesten paino laski, kehon rasvan määrä väheni ja kunto parani palvelusaikana. Edulliset muutokset fyysisessä kunnossa ja kehon koostumuksessa korostuivat ylipainoisilla ja lihavilla varusmiehillä. Nämä muutokset, erityisesti painon ja sisälmysrasvan väheneminen, olivat yhteydessä kestävyyskunnon paranemiseen. Vastaavasti kardiovaskulaaririskitekijöiden edulliset muutokset olivat yhteydessä erityisesti kestävyyskunnon paranemiseen ja vyötärölihavuuden vähenemiseen. Tämän tutkimuksen perusteella voidaan todeta, että nuorten miesten valtimosairauksien riskitekijöiden muutos on yhteydessä fyysisen kunnon nousuun. Nuoret miehet tulee saada lisäämään vapaa-ajan liikuntaa myös siviilielämässä. Keski-iässä yleistyvät valtimosairaudet ja diabetes voisivat olla huomattavissa määrin torjuttavissa vaikuttamalla nuorten miesten liikuntatottumuksiin.
