Epidemiology of what to eat in the 21st century.

The purposes of this systematic review were to present and compare recent estimates of the prevalence of overweight and obesity in school-aged youth from 34 countries and to examine associations between overweight and selected dietary and physical activity patterns. Data consisted of a cross-sectional survey of 137 593 youth (10-16 years) from the 34 (primarily European) participating countries of the 2001-2002 Health Behaviour in School-Aged Children Study. The prevalence of overweight and obesity was determined based on self-reported height and weight and the international child body mass index standards. Logistic regression was employed to examine associations between overweight status with selected dietary and physical activity patterns. The two countries with the highest prevalence of overweight (pre-obese + obese) and obese youth were Malta (25.4% and 7.9%) and the United States (25.1% and 6.8%) while the two countries with the lowest prevalence were Lithuania (5.1% and 0.4%) and Latvia (5.9% and 0.5%). Overweight and obesity prevalence was particularly high in countries located in North America, Great Britain, and south-western Europe. Within most countries physical activity levels were lower and television viewing times were higher in overweight compared to normal weight youth. In 91% of the countries examined, the frequency of sweets intake was lower in overweight than normal weight youth. Overweight status was not associated with the intake of fruits, vegetables, and soft drinks or time spent on the computer. In conclusion, the adolescent obesity epidemic is a global issue. Increasing physical activity participation and decreasing television viewing should be the focus of strategies aimed at preventing and treating overweight and obesity in youth.

Eating Pattern Analyses: The Whole Is More than the Sum of Its Parts

Objective: Identifying dietary and physical activity (PA) patterns in Russian youths and examining their dependence on gender, age, family characteristics and area of residence features. The research involved 783 school students 10–17 years of age and their parents living in the cities of Moscow and Murmansk. Using the principal component analysis, four integral indices were identified that characterized the habits and dietary patterns, PA and lifestyle. Boys, compared with girls, were more likely to consume unhealthy foods but less likely to practice malnutrition. Within the age ranges of 13–15 years old and 16–17 years old, the proportions of school students with a poor sleep pattern and low PA were higher than in children 10–12 years of age. In smoking families, children were less likely to consume healthy foods and more likely to eat unhealthy foods. In Murmansk school students, compared with their Moscow peers, a reduction in both sleep time and PA was observed less often. Our study demonstrated that the most significant factors of a balanced and healthy diet, rational daily routine and lifestyle in school students were their gender and age characteristics, as well as some contextual factors.

Heart Health: Does Diet Still Matter?

Objectives: 1) To determine eating and physical activity behaviors among students enrolled at The American School of Bangkok; 2) To identify factors associated with eating and physical activity patterns; 3) To develop a coordinated school health promotion program; and 4) To determine the effectiveness of the school health promotion program in enhancing healthful eating and physical activity among the students. Methods: A one-group pre-test/post test quasi-experimental study was conducted at the American School of Bangkok. A nutrition screening was carried out to determine students' BMI status. Socio-demographic, psychosocial, behavioral and environmental data among 72 students from 4th-6th grades were collected through a survey. Results: Findings reveal that overweight is a health problem among the students at the American School of Bangkok. A high proportion of students had poor diet. The majority of the students had low physical activity and high inactivity levels. Results indicated that factors associated with eating behavior include number of meals eaten at home, type of meals eaten at home, knowledge, attitudes/beliefs, eating self-efficacy, parental influence, parental knowledge, and parental attitudes/beliefs. Factors associated with physical activity include exercise self-efficacy, parental influence, and use of exercise/recreation center. Exercise/recreation facility use was the only important factor in inactivity among the students. Both eating and physical activity behaviors were positively associated with weight status among the participants. A school health-promotion program was identified as a strategy in improving eating and physical activity behaviors among the students. Findings from the situation analysis facilitated the development and implementation of the school health program. The school health promotion program was instrumental to improvements made in eating and physical activity behaviors among the subjects. The mobilization of all school constituents including school authorities, personnel, staff, teachers, students and parents and their participation in the program were important ingredients to the success of the school health promotion program. Conclusion: Whilst the relationship between childhood nutrition and adult disease is not yet fully understood, there is some evidence that diet and physical activity patterns affect nutritional status. The results from this study suggest that diet, physical activity and inactivity patterns are likely contributors to an increased prevalence of overweight among students in the study. The findings also imply that restaurant food consumption and non-utilization of exercise/recreation facility are important contributors to higher BMI among the students. The development and implementation of a School Health Promotion program was found to be successful in enhancing healthful eating and physical activity among the students. Recommendations: A comprehensive school health promotion program was proven to be successful in enhancing healthful eating and physical activity among the students at the American School of Bangkok. Future programs should search for ways to include caregivers in nutrition education because most modifiable behaviors of children and adolescents can [only] be facilitated by their caregivers. In addition, positive behaviors of healthful eating and physical activity that were learned at school can only be sustained through family involvement so that such behaviors are reinforced outside of school. Students and caregivers should learn how to make healthier choices when ordering from fast food restaurants. For physical activity, the use of recreation/exercise center is dependent upon the creation of fun activities for children and adolescents.

Navratri is one of the most common religious fasts observed among Hindus. A large number of people with diabetes follow Navratris fast irrespective of its health implications, often without proper education and medical advice. The quest for the scientific research on dietary advices for Hindu fasts including Navratris shows paucity of literature comparative to the dietary advices advocated during Ramadan. The eating and physical activity patterns during different fasts vary a lot depending up on social and cultural factors. Even eating pattern is not uniform among all persons following Navratris and is modified as per their region, local culture, and religious beliefs. Dietary advice during Navratris depends upon pattern of fasting, religious beliefs, and local sociocultural factors. In this review, efforts are made to provide pragmatic dietary advice for people with diabetes, modifications in the menus and cooking practices, and timings of the meals for successful blood glucose management during Navratris. This review will also help plan diet and physical activity advice for persons observing other fasts as well.

Confinement is an effective measure to control COVID-19, but it can have repercussions on lifestyle-related behaviors, especially among adolescents. Poor quality diet and low physical activity could trigger weight gain and the appearance of chronic non-communicable diseases at an early age. To investigate the changes in eating and physical activity patterns before and during the first COVID-19 confinement in Chilean adolescents. Chilean adolescents aged between 10 and 19 years were invited to answer an online survey with 47 questions about dietary habits and physical activity. The survey was answered by 420 participants and only four adolescents declined to answer it. Changes in eating patterns were evidenced, such as an increase in lunch consumption from 54.1 to 83%, and a decrease in the consumption of both healthy and unhealthy foods. Also, significant changes were observed in physical activity patterns, and an increase in the time spent sitting, from 4.7 to 5.8 hours during confinement. The first confinement for COVID-19 modified eating and physical activity patterns in Chilean adolescents towards unhealthy habits, which if maintained, could negatively affect their health and quality of life.

BackgroundSimilar to other countries, trends of decreasing levels of physical activity (PA) and an increasing prevalence of unhealthy dietary patterns are observed among girls in Poland. Better understanding of potentially inter-related behaviours within this population can help to design tailored interventions. The purpose of this study was to determine associations between PA patterns and dietary patterns in a representative sample of Polish girls.MethodsGirls aged 13-21 years (n = 1107) were randomly selected for the study. PA was assessed using International Physical Activity Questionnaire – Long (IPAQ-L). Dietary data were collected with food frequency questionnaires. PA patterns and dietary patterns were drawn separately by Principal Component Analysis (PCA). Logistic regression was used to find the associations between PA patterns and dietary patterns.ResultsFour major PA patterns (‘School/work activity’, ‘Active recreation’, ‘Yard activity’ and ‘Walking and domestic activity’) and four dietary patterns (‘Traditional Polish’, ‘Fruit & vegetables’, ‘Fast food & sweets’ and ‘Dairy & fats’) were identified. Level of PA was the highest in the upper tertile of ‘School/work activity’ pattern (mean 1372.2 MET-minutes/week, 95 % Confidence Intervals [CI]: 1285.9–1458.5). Girls in upper tertiles of ‘Yard activity’, ‘Active recreation’ and ‘School/work activity’ patterns had significantly higher chances of being in the upper tertile of the ‘Fruit and vegetables’ dietary pattern (odds ratio [OR] 2.17, 95 % CI: 1.50–3.14, p < 0.0001; OR 2.02, 95 % CI: 1.41–2.91; p < 0.001 and OR 1.76, 95 % CI: 1.24–2.51, p < 0.01 respectively; all adjusted for confounders) in comparison to bottom tertiles. Weak, but significant inverse associations were found between upper tertiles of ‘Active recreation’ and ‘Yard activity’ patterns and unhealthy dietary patterns.ConclusionsWe found associations between PA patterns and dietary patterns in the population of Polish girls. Girls with the highest adherence to the ‘School/work activity’ pattern had the highest levels of PA and presented pro-healthy dietary behaviours. School should be recognised as potentially efficient and important setting to maximise girls' PA potential. The after-school time is the area that should also be targeted to increase daily PA or to at least sustain the level of PA after completing education.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-016-3367-4) contains supplementary material, which is available to authorized users.

Eating patterns, body composition and cardiometabolic health in menopause

Pediatric overweight, dyslipidemia and insulin resistance can result from unhealthy lifestyle habits and increase morbidity and mortality in adulthood. Herein, we evaluated the relationship between diet and physical activity patterns with the metabolic health of 9-year-old school children. Measurements included anthropometry, adiposity, lipid, and glycemic profiles. Questionnaires evaluated diet and physical activity. Exploratory factor analysis (EFA) screened for diet patterns, and multilevel models evaluated diet and physical activity patterns against overweight, dyslipidemia, and insulin resistance markers across schools and children. EFA highlighted two diet patterns, Western and Traditional. Food rich in fat, salt, and sugar and fewer vegetables and fruits defined the Western pattern. The Traditional pattern, linked to healthier eating habits, had analogies to the Mediterranean diet. Overall, 39% of the children were overweight (including the obese), while 62% presented cardiovascular risk factors on their lipid profiles. Normal-weight children presented 60% high cholesterol incidence. Global insulin resistance incidence was 4.1%, but almost doubled among the overweight/obese. The Westernized diet consistently linked to worse cardiovascular risk markers, even independently of physical practice. Intensive or competitive physical activity was associated with decreased triglycerides (p = 0.003), regardless of diet. Future prospective studies are warranted to validate these results externally.

BackgroundStatistics indicate that the morbidity of breast cancer is increasing globally, and its (overall figures) incidence has now surpassed that of lung cancer for the first time. The relation between a whole dietary pattern, rather than of a single food or nutrient, and breast cancer (BC) should be examined for findings to capture the complexities of diet and the potential for synergism between dietary components. Hence, the effects of dietary patterns on breast cancer have recently attracted increasing attention.ObjectiveTo systematically review the effects of dietary patterns on breast cancer risk, prognosis, and quality of life in survivors.MethodsThis systematic review was conducted following PRISMA guidelines and was registered in PROSPERO. Data from Ovid, China Biomedical Literature Database, Wanfang Data Knowledge Service Platform, CNKI, PubMed, Weipu, The Cochrane Library, Duxiu Data, ProQuest, Embase, Web of Science, and Scopus Database were retrieved and evaluated.ResultsA total of 47 studies that investigated the association between eating patterns and breast cancer were identified. Ten studies evaluated the effect of the model on treatment outcome and prognosis of breast cancer and two cross-sectional studies examined the influence of dietary patterns on quality of life. The resulting favorable dietary patterns were shown to regulate metabolic biomarkers, antioxidants, anti-inflammatory agents, and protective genes, and inhibit cell proliferation and invasion.ConclusionNumerous studies have examined the effects of healthy eating, plant-based, anti-inflammation, low-fat, and other favorable dietary patterns in relation to breast cancer. However, few studies reported significant associations and the studies had limitations, suggesting that the current findings should be interpreted with caution.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/, CRD4202 2350171.

Obesity is a major cause of diseases such as diabetes, heart disease, and other metabolic disorders. A preliminary study conducted on 15 police officers from the Central Kalimantan Police Department revealed that 9 officers (60%) were obese, while 6 officers (40%) were not. Among the 9 obese officers, 8 admitted to rarely engaging in regular physical activity and frequently consuming fast food, while 1 officer was in the process of losing weight by exercising and maintaining a healthy diet. The causes of obesity include physical activity and dietary patterns. The objective of this study was to analyze the relationship between physical activity and dietary patterns and the incidence of obesity among police officers at the Central Kalimantan Police Department. Methods: This correlational study used a cross-sectional approach to examine the relationship between physical activity and dietary patterns and the incidence of obesity among police officers at the Central Kalimantan Police Department. Data collection instruments included questionnaires and BMI measurements. The sample consisted of 196 police officers classified as overweight and obese, selected through simple random sampling. The data were analyzed using the Chi-Square correlation test. Results: The study found a significant relationship between physical activity (p-value = 0.000, 83.6%) and dietary patterns (p-value = 0.000, 73.8%) and the incidence of obesity among police officers at the Central Kalimantan Police Department. Conclusion: Physical activity and dietary patterns are significantly related to the incidence of obesity among police officers at the Central Kalimantan Police Department. The role of nurses in addressing obesity should begin with an accurate assessment of family care patterns, ensuring that interventions and education provided are effective, and prioritizing promotive and preventive measures to address obesity and prevent the emergence of chronic diseases.
