Exercise and eating habits among urban adolescents: a cross-sectional study in Kolkata, India

Classroom intervention to improve behavioral intention toward regular physical activity among adolescents

Background

During adolescence, a critical phase in human life, the groundwork for a healthful future is established. Physical inactivity poses a significant risk factor for non-communicable diseases (NCDs) and related mortality worldwide. To assess adolescents' behavioral intentions regarding regular physical activity, the Theory of Planned Behavior (TPB) examines 'Attitude,' 'Subjective norm,' and 'Perceived behavioral control.' Utilizing TPB, this study focuses on evaluating the impact of a school-based health promotion intervention on behavioral intentions toward physical activity among urban adolescents in West Bengal, India.

Methods

A school-based nonrandomized controlled interventional study with parallel group design was conducted among adolescents aged between 12 and 16 years. Behavioral intention towards performing regular physical activity was determined with the measurements of the constructs from the TPB. Cluster analysis was conducted using measurements from both the intervention and control groups. Participants with higher mean scores in the constructs were classified as intenders, while the rest were considered non-intenders. The intervention's impact was evaluated by calculating the Relative Risk (RR) through a generalized linear model with robust standard error estimates, to ascertain the probability of belonging to the higher intention cluster.

Result

Following the intervention, construct-wise scores improved significantly, particularly the perceived behavioral control mean score in the intervention group. The Relative Risk (RR) of becoming an intender for regular physical activity in the intervention group was 1.24 (95% CI: 1.04-1.48) when compared to the control group.

Conclusion

Health Promoting Schools has been recognized as a strategic and cost-effective vehicle to promote positive development and healthful living, and the current evidence suggests they can effectively reduce the emergence of significant NCD risk factor like physical inactivity. Schools must establish strong partnerships with diverse stakeholders to address barriers beyond the school environment and enhance their control over critical issues.

Nutritional status of school-age children (5-19 years) in South Asia: A scoping review

Information on malnutrition for school-age children and adolescents (5-19 years) in South Asia is fragmented and inconsistent, which limits the prioritization of nutrition policies, programmes and research for this age group. This scoping review aimed to synthesize existing evidence on the burden of malnutrition for children and adolescents aged 5-19 years in South Asia, and on interventions to improve their nutritional status. Cochrane Library, EMBASE, Medline and Google Scholar were systematically searched for articles published between January 2016 and November 2022. Eligible studies reported the prevalence of undernutrition, overweight/obesity, micronutrient deficiencies and unhealthy dietary intakes, and interventions that aimed to address these in South Asia. In total, 296 articles met our inclusion criteria. Evidence revealed widespread, yet heterogeneous, prevalence of undernutrition among South Asian children and adolescents: thinness (1.9%-88.8%), wasting (3%-48%), underweight (9.5%-84.4%) and stunting (3.7%-71.7%). A triple burden of malnutrition was evident: the prevalence of overweight and obesity ranged from 0.2% to 73% and 0% to 38% (with rapidly rising trends), respectively, alongside persistent micronutrient deficiencies. Diets often failed to meet nutritional requirements and high levels of fast-food consumption were reported. Education, fortification, supplementation and school feeding programmes demonstrated beneficial effects on nutritional status. Comprehensive and regular monitoring of all forms of malnutrition among children and adolescents, across all countries in South Asia is required. Further, more large-scale intervention research is needed to ensure policy and programmes effectively target and address malnutrition among children and adolescents in South Asia.

Association of Screen Time Usage and Physical Activity With Overweight and Obesity Among School-Going Children in Uttar Pradesh

Background Being overweight during childhood refers to excess weight for a given height, while obesity denotes excess body fat. These conditions stem from surplus calorie intake and insufficient physical activity. Escalating pediatric obesity is linked to modern sedentary lifestyles, marked by increased screen time, reduced exercise, and poor diets. Once believed to be a concern in affluent nations, obesity now affects developing countries like India due to changing eating habits and urbanization. Despite limitations in measurement tools, such as body mass index (BMI) and waist circumference, recognizing sedentary behaviors such as prolonged screen time is pivotal. The rapidly rising prevalence of pediatric obesity has become a major public health concern; therefore, we conducted this study to determine the prevalence and association of screen time usage with being overweight in school-going children (aged 8-15 years). Methodology This observational, cross-sectional study was conducted in Greater Noida, Uttar Pradesh over 18 months (January 2019 to June 2020) after obtaining institutional ethical committee approval. Participants were 8 to 15-year-old students from three co-educational secondary schools in the region. Children with motor or developmental disabilities were excluded. Written informed parental consent and school permission were secured. Anthropometric measurements included weight (SECA 874 U scale) and height (SECA213 stadiometer), which were used to calculate BMI. Overweight/obesity status followed the Indian Academy of Pediatrics guidelines. A validated questionnaire assessed screen time, and a validated Physical Activity Questionnaire measured physical activity. Both questionnaires were administered twice to validate data. SPSS version 23.0 (IBM Corp., Armonk, NY, USA) was used for data analyses (descriptive, t-test, analysis of variance (ANOVA) test, and chi-square test). P-values <0.05 were considered significant. Results This study involved 604 participants. Among them, 47.7% had a normal BMI, 37.4% were overweight, and 14.9% were obese. Most participants (97.4%) reported screen time of over 60 minutes daily, while 2.6% reported lower screen time. ANOVA revealed significant differences in daily (F = 16.014, p < 0.001) and weekly (F = 16.175, p < 0.001) screen time among BMI categories. Low physical activity was prevalent (97.7%). ANOVA showed significant variations in physical activity scores and durations (p < 0.001), with normal-weight individuals exhibiting higher levels. Conclusions The rising prevalence of overweight among children underscores the need for early intervention strategies, emphasizing the importance of reducing screen time and promoting increased physical activity. These measures are critical in addressing the growing challenge of being overweight during childhood and its potential long-term health implications.

School-based intervention on behavioral intention of adolescents regarding healthy diet in India

Introduction

Adolescence is a distinctive period of life when intense physical, psychological, and cognitive development occurs. A healthy diet helps prevent various forms of malnutrition and non-communicable diseases (NCDs) like diabetes, heart disease, stroke, and cancer. The current study aimed to assess the change in behavioral intentions (measured based on the TPB) toward healthy dietary practices through health promotion intervention among adolescents studying in selected schools in an urban area of West Bengal, India.

Methods

The current study was a non-randomized controlled interventional study conducted among adolescents in either seventh, eighth, ninth, or tenth grades and aged between 12 and 16 years. Two-step cluster analysis with maximum likelihood estimation identified the intenders of a healthy diet. The intervention effect was measured using Relative Risk (RR) for being in the higher intention cluster through Generalized Linear Model (GLM) with a log-linear link under Poisson distribution assumptions and robust standard errors. A P-value of 0.05 or lesser was considered statistically significant.

Results

There was no statistically significant difference in the mean score of "Attitude" in both groups. The mean score of "Subjective Norm" among the intervention group increased after intervention, and the difference was statistically significant. The mean score of "Perceived behavioral control" in the intervention group increased after the intervention, but the difference was statistically not significant. The intervention group's post-intervention proportion of intenders increased, and the difference was statistically significant. The relative risk of becoming an intender for healthy diet consumption in the Intervention group compared to the Control group was 2.07 (1.44-2.97).

Conclusions

The intervention package effectively brought about a positive change in behavioral intention toward healthy dietary practices among adolescents. Model-based and construct-oriented intervention packages can be adopted in school-setting to promote behavioral intention toward a healthy diet.

Lifestyle practices predisposing adolescents to non communicable diseases in Delhi

Background

Globally the prevalence of non- communicable diseases is on a rise. Adolescents are vulnerable to such diseases later on in life because of the susceptibility to behavioural risk factors like insufficient physical activity, unhealthy dietary practices and tobacco and alcohol consumption during this transition stage of their life. Adolescents who are from low-income families are also at increased risk of dual states of malnutrition such as underweight and obesity. So, this study aimed to estimate the prevalence of such behavioural risk factors among adolescents of low-income urban areas of Delhi.

Methodology

A cross-sectional study was conducted among 264 adolescents (10-19 years) of low-income Urban areas of Delhi.

Results

A total of 122 (46.2%) boys and 142 (53.8%) girls were enrolled in the study. The mean age of adolescents were 14.2 ± 2.4 years. The most prevalent NCD risk factor was physical inactivity (98.1% [96.4-99.7])). The screen time for television was significantly higher among boys than girls (p value 0.022). An age stratified analysis of risk factors showed that the intake of carbonated drinks (p value 0.026) and social media utilisation time (p value 0.037) was significantly higher among late adolescent boys (≥15 years) compared to early adolescents.

Conclusion

There is high prevalence of physical inactivity and unhealthy dietary behaviours among adolescents which could be a warning sign for prompt actions as they are at risk of NCD in future. Hence healthier practices should be promoted among adolescents at community level.

A School-based survey among adolescents on Dietary pattern, Exercise, and Knowledge of Cardiovascular risk factors (ADEK) Study

Background. Cardiovascular disease is a global emerging problem and its risk starts in children and adolescents. Adolescents have modifiable cardiovascular risk factors that have been found globally, and nationally, and early intervention programs may be able to lower these risks for both individuals and populations. Accurate risk factor evaluation at the individual level is crucial in this situation for the prevention of cardiovascular disease. Objective. The study aimed to investigate cardiovascular disease knowledge and to determine physical activity, and dietary patterns among school-going adolescents in Arakkonam, Tamil Nadu, India. Methods. A school-based cross-sectional survey was conducted to assess cardiovascular disease knowledge among 500 adolescents aged 10-18 from public schools. The study period was from September 2021 to February 2022. The measurement taken on anthropometrics such as height, weight, body mass index, and bio-physiological measurement as blood pressure, structured questionnaire assessed for knowledge, dietary questionnaire assessed previous week food consumption which the investigator developed, and physical activity standard questionnaire assessed the past week’s exercise level. Data were analyzed using IBM Statistical Package for Social Sciences version 20. Results. The mean study population age was 13.7±1.7, 53% were boys, and 47% were girls. Factors like age 16-18 years (p=0.01), site of residence from urban (p=0.001), education of teenagers (p=0.01), and family history of cardiovascular disease (p=0.001) are significantly correlated with the level of knowledge score, with better-educated adolescents having fair knowledge score than others. Level of knowledge score and demographic traits are associated with physical activity, such as 16 to 18 years (p=0.03), living in an urban region (p=0.03), being in a joint household (p=0.001), adolescents who are at higher secondary (p=0.02), and having a family history contribute more to cardiovascular disease (p=0.001) than other variables. Mean days eating diets were egg (4.18±2.27), vegetables (3.92±0.93), milk products (3.85±1.87), fried foods (3.75±1.25), toffees, and chocolates (3.35±1.81) all had higher percentages of consumed foods than others. Conclusion: There is a risk of cardiovascular disease higher among adolescents. Still a need for school-based primordial preventive educational approaches needed to improve to curb this burden.

Co-occurrence of non-communicable disease risk factors and its determinants among school-going adolescents of Kathmandu Metropolitan City

Background

Adolescence is a critical transition in human growth and adolescents tend to engage in various risky behaviors which are likely to continue into adulthood. Co-occurrence of non-communicable disease risk factors has the potential to increase risks of chronic disease comorbidity and increased mortality in later life. Behavioral risk factors are adopted due to changes in lifestyle and adolescents are more prone to acquire them. This study aimed to determine the prevalence and associated factors of co-occurrence of non-communicable disease risk factors among school-going adolescents of Kathmandu Metropolitan City.

Methods

We conducted a cross-sectional study among school-going adolescents of Kathmandu Metropolitan City in January/February 2020. We used stratified random sampling to select 1108 adolescents studying in 9, 10, 11, and 12 grades. We used Global Schools Health Survey tools to collect data. We entered data in EpiData 3.1 and exported it into Statistical Package for Social Science (SPSS) version 20 for statistical analysis. We estimated prevalence of NCDs risk factors and co-occurrence of risk factors. We applied multivariate multinomial logistic regression analysis adjusting for age, gender, ethnicity, religion, education, type of school, and parental education to determine factors associated with co-occurrence of NCDs risk factors.

Results

The prevalence of physical inactivity, unhealthy diet, harmful use of alcohol and tobacco among school-going adolescents were 72.3% (95%CI: 69.6–74.9), 41.1% (95%CI: 38.2–44.0), 14.8% (95%CI: 12.8–17.0) and 7.8% (95%CI:6.3–9.5) respectively. The adolescent with co-occurrence of two or more risk factors was 40.7% (95%CI: 37.8–43.7). The school-going adolescents who were in higher age group (AOR = 1.72, 95% CI- 1.06, 2.77), Hindus (AOR = 1.78, 95% CI-1.09, 2.89), other than Brahmin/Chhetri by ethnicity (AOR = 2.11, 95% CI-1.39, 2.22) and with lower education level of mothers (AOR = 2.40, 95% CI- 1.46,3.98) were more likely to have co-occurrence of NCDs risk factors after adjusting for all socio-demographic variables.

Conclusion

The co-occurrence of non-communicable disease risk factors was high among school going adolescents and was associated with age, religion, ethnicity and mother’s education. Integrated and comprehensive interventional programs should be developed by concerned authorities.

Effectiveness of structured interventional strategy for middle-aged adolescence (SISMA-PA) for preventing atherosclerotic risk factors—A study protocol

Background

Atherosclerotic risk starts at an early stage in adolescents and interventions on adolescents’ lifestyles are most important. The pandemic of obesity-related morbidities like atherosclerosis among young adults and atherosclerotic risk factors for middle-aged adolescents in India is known. Yet, there is a lack of cost-effective and integrated intervention programs to treat this important health problem.

Objective

The main objective of this study is to evaluate the effect of a 12-week structured interventional strategy program, containing integrated education and supervised physical activity interventions for middle-aged adolescents.

Methods/design

This will be a school-based pre-experimental one-group pre-post time-series research design. The sample size is estimated to include 154 adolescents of 10^th to 12^th grade; aged 15–17 years will be grouped as a single arm. Data will be collected from July 2021 to January 2022. The intervention duration will be 3 months. The following measures will be evaluated before, during, and after intervention: knowledge, body mass index, level of physical activity, dietary habits, and sedentary activity.

Discussion

We believe that the structured interventional strategy approach which includes education related to atherosclerosis, physical activity, dietary habits, and sedentary activity, and cost-effective physical activity training will be more effective in preventing atherosclerotic-related changes among middle-aged adolescents. Further, this kind of approach may be applied in similar study areas elsewhere in India.

Why The Knowledge of Indian School-Going Adolescents Regarding NCDs is Not Transforming into Lifestyle Changes?

Background

There is a paucity of research to demonstrate the quantification of adolescents' risk behavior toward Non-Communicable Diseases (NCD) in India. This study aims to explain the knowledge of school-aged adolescents about NCD and whether their knowledge is truly translating into lifestyle changes and if not, what are the potential underlying factors responsible for that.

Methodology

A school-based cross-sectional study was conducted on adolescents in Jodhpur district, India, in grades 6 to 12. The data was gathered via a semi-structured questionnaire. The participant's weight and height were assessed using a digital weighing machine and a stadiometer, respectively. SPSS v.23 was used to analyze the data. Univariate (chi-square) and multivariate (logistic regression) analysis were used to quantify knowledge and risk factors, and inferences were derived.

Results

A total of 1010 students participated in the study. The mean scores of knowledge and risk behavior were 32.82±6.43 (out of 40) and 9.23+2.63 (out of 30), respectively. Adolescent risk behavior and knowledge were not found to be significantly related. Physical activity, spending fewer hours sitting, not skipping breakfast, and habit of fruit and vegetable consumption were significant factors for a healthy lifestyle among them.

Conclusion

Due to differences in underlying predictors, adolescents' understanding of NCDs did not translate into healthy lifestyle modifications. These findings highlight the importance of developing tailored interventions for adolescents that target identified risk domains.

Socioeconomic, intrapersonal and food environmental correlates of unhealthy snack consumption in school-going adolescents in Mumbai

Background

Unhealthy snacking habits in adolescents are typically triggered by obesogenic food environments and possibly perpetuated through interactions between socio-environmental factors and personal perceptions, attitudes, and motivations to change eating behaviors. This study attempted to address the knowledge gap regarding the association of intrapersonal, socioeconomic, and food environmental characteristics with unhealthy snack consumption in Indian adolescents, presenting several targets for effective interventions.

Methods

A representative sample of 10–12 years old adolescents (n 712) completed a cross-sectional survey including eating habits, characteristics of school and home food environments, and perceptions related to affordability, convenience, and barriers within the food environments. The frequency of unhealthy snack consumption was assessed using a validated qualitative food frequency questionnaire. Multivariate regression analyses determined the associated factors of unhealthy snack consumption in adolescents attending private and public schools.

Results

The mean age of adolescents was 10.9 (1.1) years, 48.2% were girls and 53.9% attended private schools. The most frequently consumed unhealthy snacks were biscuits/ cookies (5.2d/wk) followed by wafers (3.4d/wk) and Indian fried snacks- samosa/ vada pav (2.8 d/wk). Among the public-school adolescents, the odds of unhealthy snack consumption were 0.89 times lower when meals were had frequently at the dinner table and 4.97 times higher when the perceived barriers related to the affordability of healthy snacks were greater. Maternal education (OR 0.78, 95% CI 0.66–0.82, p < 0.001), family income (OR 2.15, 95% CI 1.98–2.32, p < 0.001), availability of unhealthy snacks (OR 2.98, 95% CI 1.36–3.46, p < 0.001) and fruits (OR 0.57, 95% CI 0.49–0.69, p < 0.001) at home, having evening meals together (OR 0.71, 95% CI 0.63–0.81, p 0.031), and perceived parental control during mealtimes (OR 0.67, 95% CI 0.62–0.72, p < 0.001) were associated with unhealthy snack consumption in adolescents attending private schools.

Conclusions

The results highlighted a pervasiveness of unhealthy snacks in adolescents’ food environments. Improving provisions and affordability of fruits and healthy snacks at schools, encouraging family mealtimes, and limiting the availability of unhealthy snacks at home whilst addressing the perceived barriers within food environments, and inculcating self-efficacy skills can improve snacking habits in Indian adolescents, irrespective of socioeconomic backgrounds.

Predicting exercise behaviors and intentions of Taiwanese urban high school students using the theory of planned behavior

PURPOSE

This study applied the Theory of Planned Behavior to predict exercise behaviors and intentions of teenagers and analyzed sex differences.

DESIGN AND METHODS

A prospective study design was employed to survey tenth-grade students in Taipei, Taiwan. The 951 participants reported their exercise attitudes, subjective norms, perceived behavioral control (PBC), and intentions, and their exercise behaviors were tracked 6 months later.

RESULTS

Results revealed that 22.1% of all students and more male students than female students exercised for ≥30 min/day on 5 or more days/week. Hierarchical multiple regression analyses demonstrated that intentions, PBC, attitudes, and subjective norms explained 32.5% of the variation in exercise behavior (p < .001). Intentions, attitudes, and PBC were related to exercise behavior regardless of sex. Attitudes, subjective norms, and PBC explained 67.0% of the variation in intentions (p < .001). Attitudes and PBC were related to intentions regardless of sex.

CONCLUSIONS

The findings support that the main constructs of the Theory of Planned Behavior can effectively predict regular exercise intentions and behaviors among adolescents.

PRACTICE IMPLICATIONS

The results can serve as a reference for nurses and other healthcare professionals when formulating effective strategies to encourage adolescents to engage in exercise practices.

Prevalence of Excessive Weight and Underweight and Its Associated Knowledge and Lifestyle Behaviors among Urban Private School-Going Adolescents in New Delhi

With rapid urbanization and the Indian nutrition transition, Indian adolescents face a high risk of developing an energy imbalance. This study aims to assess the prevalence of excessive weight, underweight, and associated knowledge and lifestyle behaviors among private school-going adolescents in Delhi. A cross-sectional study was conducted in students (6th–7th grades) of eight randomly selected private schools in Delhi, India in 2019. A self-administered survey was used to assess students’ dietary-and-physical-activity-related knowledge and behavior. Anthropometric measurements (height, weight, and waist circumference) were also conducted. Out of 1567 participants, 7.2% were underweight, 61.3% normal, and 31.5% excess in weight. Underweight was associated with significantly more eating whilst studying for exams (relative risk ratio (RRR) 1.7 (1.0–2.9)). Excessive weight was associated with less incorrect knowledge on behaviors causing overweight (RRR 0.7 (0.5–0.9)), more often reading nutritional labels of packed food items (RRR 0.6 (0.4–0.9)), and less frequent vegetable-intake (RRR 0.7 (0.4–0.9)). Underweight students showed more suboptimal knowledge and unhealthy behaviors, whilst students with excessive weight showed more correct knowledge and healthy behaviors. This study highlights the immediate need for effective health-promoting interventions focused on the importance of healthy lifestyle at least in underweight adolescents.

Poor Dietary Habits: A Function of Online Food Delivery Fad among Medical and Dental College Students in India

Background

Globalization has impacted our food choice and the booming online food industry has made it available at the click of a button. Students staying away from home often fail to maintain a healthy diet and lifestyle, impacting their health.

Methods

A survey was conducted amongst interns of medical and dental colleges in Delhi. Simple Random Sampling was done to select every alternate intern as per the list provided by the colleges. The survey included questions on dietary, fitness and food hygiene habits and dental history. Demographic details such as height weight and living arrangements were collected. Dietary habits score and Fitness & Food hygiene score was calculated based on pre-set criteria. Association of poor dietary habits and hygiene with BMI, living conditions and dental history was determined.

Results

One-fourth of the population was either overweight or obese. Poor, fair and good dietary habits was seen in 8.9%, 69.8% and 21.4% respectively. Poor, fair and good fitness and food hygiene was seen in 56.3%, 39.6% and 4.2% respectively. Obesity was significantly associated with poor fitness scores and with tendency to order junk food. Consumption of sugary food was associated with positive dental history, and those living with parents displayed good dietary habit score.

Conclusion

Students with high stress levels and living away from home are susceptible to poor dietary routine which impacts both their health and academic performance. Identifying these problems and triggers which induce such unhealthy lifestyle behaviour can go a long way in controlling the resultant health problems.

Impact of a behaviourally focused nutrition education intervention on attitudes and practices related to eating habits and activity levels in Indian adolescents

OBJECTIVE

To evaluate the effectiveness of a behaviourally focused nutrition education (NE) intervention based on the Health Belief Model (HBM) to improve knowledge, attitudes and practices (KAP) related to eating habits and activity levels in 10–12-year-old adolescents in Mumbai, India.

DESIGN

School-based cluster randomised controlled trial. The experimental group (EG) received weekly NE and three parent sessions over 12 weeks; no sessions were conducted for the control group (CG). The theoretical framework of HBM and focus group discussion results guided the development of behaviour change communication strategies and NE aids. KAP were measured using a validated survey instrument, administered at baseline and endline in EG and CG. Paired and independent t tests determined within-group and between-group changes in pre–post scores.

SETTING

Two aided and two private schools that were randomly allocated to either an EG or CG.

PARTICIPANTS

Adolescent boys and girls (n 498; EG n 292 and CG n 206).

RESULTS

EG reported improvements in mean knowledge (39·3%), attitude (7·3 %), diet (9·6 %) and activity practice (9·4%) scores from pre to post intervention. No significant changes were observed in CG. Significant improvements in scores associated with perceived benefits, barriers and self-efficacy, breakfast and vegetable consumption, and moderate-to-vigorous activities were observed in EG.

CONCLUSIONS

Integrating NE into the academic curriculum and adopting evidence-based lessons that entail targeted information delivery and participatory activities can improve knowledge, foster right attitudes and facilitate better eating and activity-related practices in Indian adolescents.

Effectiveness of Music in Enhancing Nutrition Education Outcomes Among Adolescents

OBJECTIVE

To determine the effectiveness of healthy eating songs (HES) in improving adolescents' healthy eating knowledge, attitude, and practice.

DESIGN

Pretest-posttest quasi-experimental nonequivalent group design. Students from 2 of the selected schools (n = 37 and n = 35) received nutrition education using conventional classroom instruction and HES, whereas the other 2 (n = 30 and n = 31) received theirs using conventional classroom instruction only.

SETTING

Ibadan, Nigeria.

PARTICIPANTS

A total of 133 students selected from 4 junior secondary schools participated in the study.

MAIN OUTCOME MEASURES

Changes in healthy eating knowledge, attitude, and practice at the school level.

ANALYSIS

Independent t tests were used for analyzing summary data, whereas the linear mixed model was used to analyze the fixed effects of predictor variables at P < 0.05.

RESULTS

Nutrition education had a significant effect on knowledge (F = 65.7, P < 0.001), attitude (F = 85.2, P < 0.001), and practice (F = 131.5, P < 0.001). Improvement in knowledge, attitude, and practice was observed in both groups. However, the intervention group performed better than the comparison group in knowledge (95% confidence interval [CI], -0.1 to 2.8), attitude (95% CI, 1.7-9.7), and practice (95% CI, 2.8-5.8). Geographical location had a significant effect on knowledge (F = 7.1, P = 0.005). Interaction effect of treatment and geographical location was significant on knowledge and attitude of students.

CONCLUSIONS AND IMPLICATIONS

The use of HES may be an effective way of improving adolescents' healthy eating knowledge, attitude, and practice. However, testing culturally appropriate HES in more diverse audiences is warranted.

A study on physical activity by a need-based curriculum for students in a rural area of West Bengal

BACKGROUND

Students must be made aware about the essentiality of optimum level of physical activity and the fact that it is the key to good health and an important technique to prevent and control a lot of noncommunicable diseases including depression and other related mental ill-health.

MATERIALS AND METHODS

It was an institution-based intervention study among 187 Madrasah students of classes VII and VIII, conducted in five-phase assessment of the training needs of Madrasah students on different aspects of healthy lifestyle, development of a need-based module to be used by teachers to impart training of students through classroom setting, training of teachers to use the module to train students, training of students by the trained teachers in classroom setting, and evaluation of effectiveness of the training module.

RESULTS

The mean pretest knowledge score in study Madrasah was 2.64 ± 1.35 (Mean ± SD) and post test score was 4.13 ± 0.88 (Mean ± SD). In paired t-test, t-value was 13.54 and P < 0.05 with effect size of 1.370 (Cohen's d). Practice related to the mean score in pretest was 2.38 ± 1.08 and posttest score was 2.73 ± 1.03. In paired test, t-value was 6.25 and P < 0.05 with effect size of 0.458 (Cohen's d).

CONCLUSIONS

The study revealed the effectiveness of training by teachers using the module developed by the researcher to address significant changes in lifestyle-related issues.

Are our rural adolescents eating healthy?: Implications for redesigning school health interventions - A cross sectional study in rural Coimbatore

Background

Adolescence is a period of transition where independence in thinking and behavior is established and food choices that are made are followed for several years, and this can influence their health in adulthood. Hence, understanding the eating habits are necessary to plan effective nutritional interventions in adolescents.

Objectives

The main objective of the study is to find out the extent of malnutrition among rural adolescents as well as evaluate their eating habits against recommended dietary food groups and to compare eating habits across gender and age groups.

Methods

A cross-sectional study was done among 1425 adolescents from 13 rural schools from 2014 to 2015, and the variables considered in this study were age, sex, body mass index (BMI), and the eating habits of the adolescents.

Results

Undernutrition was seen among 23% and overweight/obesity among 8% of adolescents. The habit of taking milk and milk products, fruits, and green leafy vegetables were very poor among the adolescents. Significant association was found between eating habits and BMI. Furthermore, late adolescents had better eating habits, and significant gender difference was seen in certain eating habits.

Conclusions

The study shows that it is possible to understand the gaps in eating habits of adolescents, and this can be used to plan tailor-made nutritional interventions to adolescent groups as their eating habits are different and have long-term nutritional and health implications.

Food insecurity is associated with lower adherence to the Mediterranean dietary pattern among Lebanese adolescents: a cross-sectional national study

PURPOSE

To derive dietary patterns (DPs) of Lebanese adolescents (10-18 years) and evaluate associations between identified DPs and household food insecurity (HFI).

METHODS

Data on adolescents (n = 693) were drawn from a national survey conducted in 2015 on a representative sample of Lebanese households with children. In addition to a sociodemographic questionnaire, data collection included the validated Arabic-version of the Household Food Insecurity Access Scale, used to evaluate HFI. Dietary intake was assessed using a 187-item validated food frequency questionnaire. Associations between HFI scores and DPs were examined using multiple linear regressions.

RESULTS

HFI was observed in 55.2% of the study sample. Two DPs were derived among adolescents: Western and Lebanese-Mediterranean (LM). The Western DP was characterized by higher consumption of sweetened beverages, fast foods, sweets, and refined grains, whereas the LM DP was characterized by higher intakes of fruits, vegetables, dairy products, and whole grains. Scores of the Western DP were negatively associated with fiber, calcium, iron, and vitamins A and D, while the LM DP scores were positively correlated with fiber, proteins, iron, calcium, and vitamins A and D (p < 0.01). LM DP scores were also negatively correlated with total fat, saturated and polyunsaturated fats, p < 0.05. After adjustment for sociodemographics, multiple linear regression showed that higher HFI scores were associated with lower adherence to LM DP among adolescents (β = - 0.026, 95% CI - 0.046, - 0.006).

CONCLUSIONS

HFI was associated with lower adherence to the Mediterranean pattern among Lebanese adolescents. Preventive strategies are needed to promote better diet quality among food-insecure youth.

Prevalence of low physical activity, its predictors and knowledge regarding being overweight/obesity: A community-based study from urban South India

INTRODUCTION

Physical inactivity is the fourth leading risk factor for mortality and morbidity as per the World Health Organisation (WHO). The current study was conducted in the city of Erode, Tamil Nadu, South India, to estimate the prevalence and predictors of low physical activity (LPA) and assess their knowledge with regards to being overweight/obesity.

METHODS

It was a cross-sectional study conducted over 24 months from July 2015 to June 2017. Multi-stage random sampling was done in 12 randomly chosen corporation wards. All consenting individuals above 18 years of age were included. Data were collected using a semi-structured questionnaire incorporating the validated International Physical Activity Questionnaire (IPAQ).

RESULTS

For the study, 489 individuals were screened and 461 were included. Prevalence of LPA was 49.9% (95% confidence interval [CI]:45.34%, 54.46%). The significant predictors (adjusted odds ratio [OR] [95% CI]) of LPA were patient education 1.129 (1.006, 1.2670); unemployment (2.418 [1.610, 3.631]) and knowledge score (5.172 [1.314, 9.423] 27). In the knowledge assessment, 60.3% of the participants scored less than 50%. The significant predictors of poor knowledge were marital status (unmarried) (3.857 [1.341, 11.091]), lower educational status (1.191 [1.009, 1.362]) and low socioeconomic status (SES) (1.050 [1.005, 1.121]).

CONCLUSION

Prevalence of LPA in our population is fairly high and there is gross knowledge inadequacy.

Lifestyle and risk behaviors for chronic noncommunicable diseases among healthcare undergraduates in Midwest, Brazil

This study aimed to assess the lifestyle of undergraduate university students, and to investigate the prevalence of risk behaviors for chronic noncommunicable diseases. This cross-sectional study took place in Brasilia, with 2.163 healthcare undergraduates. We used a self-administered questionnaire for demographic variables, social class, behavioral data, self-perception of health and self-reported diseases. Given a total of 2.163 students, 69.3% were female, 65.4% were 20-29 years, men smoked more cigarettes (p < 0.01) and used more alcohol than women. We found significant differences in the consumption of beans (p < 0.04) and full-fat milk (p < 0.01) between females and males. Women also had more sedentary lifestyles (p < 0.01) and showed higher prevalences of overweight (33.8%) and obesity (5.0%). Students who did not engage in physical activity were more morbidities, overweight (p = 0.03), consumed more soft drinks (p < 0.01) and meat with excess fat (p = 0.01). University students were found to have unhealthy lifestyles. There is an urgent need for both a formulation and implementation of public health policies to promote health and improve student quality of life (QoL).

Diet, Physical Activity, and Screen Time among School Students in Manipur

Context:

Adolescence is a critical time in the development of lifelong healthy eating and exercise habits. The high prevalence of adolescents exposed to excessive screen time is a matter of concern because of its association with several health problems, such as overweight and obesity, alterations in blood glucose and cholesterol, poor school performance, decreased social interaction, and lower levels of physical activity.

Aims:

The aim of this study is to identify the lifestyle behaviors of young adolescents focusing on physical activity, diet, and screen time.

Settings and Design:

A cross-sectional study was conducted among 929 students of Class VII and VIII in schools in Imphal West and Kangpokpi districts of Manipur.

Subjects and Methods:

Data collection was done by questionnaire method.

Statistical Analysis Used:

The data were analyzed using IBM SPSS for Windows, Version 21.0. Armonk, NY, USA.

Results:

Seven in 10 of the students had inadequate physical activity at school and inadequate physical activity outside school. About 56.9% of the students have a smartphone, whereas one-third of them have Facebook and WhatsApp accounts. Only 5.8% were eating a healthy diet. Females and day scholars were less physically active. Males those staying in a nuclear family, less family income, and more number of siblings were found to have unhealthy dietary habits.

Conclusions:

Less than half of the students were physically active and only six out of 100 the students were eating a healthy diet.

Noncommunicable Diseases among School-going Adolescents: A Case Study on Prevalence of Risk Factors from Sabarkantha District of Gujarat, India

Background:

The increasing burden of noncommunicable diseases (NCDs) and large proportion of adolescent population in India; crafts the dynamics of NCD risk factors. Most of the NCD risk factors are behaviorally acquired which are due to change in lifestyle during adolescent age groups.

Objective:

This study aims to determine the prevalence of risk factors among school-going adolescents in one of district of Gujarat state, India.

Subjects and Methods:

This is a cross-sectional study conducted among sampled schools of Sabarkantha district of Gujarat, India, during September–December 2016. A total of 484 school-going adolescents were screened for body weight, height, blood pressure, and some information of sociodemographic, lifestyle habits, and family history were collected through a structured questionnaire in vernacular language. Data were managed with SPSS version 20.

Results:

This study documents that not having fruits and not doing physical activities daily are the major risk factors of NCDs among school-going adolescents of Sabarkantha district, Gujarat. In addition to this, also it has been documented that there are differential standards for body mass index (BMI) available for adolescents and have been used extensively in various studies. This study provides an insight to these three major BMI standards and their differences in measurement for the school-going adolescents.

Conclusions:

This study recommends promoting healthier practices for prevention of NCD lifestyle risk factors among school-going adolescents and it also recommends standardizing the BMI measurements for adolescents for India.
