Development and validation of a questionnaire measuring knowledge, attitudes, and practices (KAP) to healthy eating and activity patterns in school children (HEAPS)

Individual-Level Drivers of Food Choices and Diet Quality Among Adolescents in Urban West Africa: Evidence From Accra, Ghana

Diet quality is influenced by multiple individual factors, but their relative strength and importance remain unclear. We investigate the associations between five domains of individual factors (economic, cognitive, aspirational, situational and consumer behaviour) and diet intake of adolescents in Accra, Ghana. A cross-sectional survey among Junior High School (JHS) students (n = 409, mean age 14.3 years ± 1.28 (SD)) in Accra, Ghana, was conducted. Data on diet intake, knowledge, attitude and practices (KAP) and socioeconomic background characteristics were collected. Adjusting for other factors, students' total budget was positively associated with food group diversity (β = 0.12, 95% confidence interval [CI] 0.09-0.15) but inversely associated with diet quality (β = -0.07, 95% CI -0.11 to -0.03). Positive attitude towards nutrition and healthy eating was inversely associated with unfavourable diversity (β = -0.17, 95% CI -0.31 to -0.03). Differences between negative deviants relative to positive deviants were determined by attitude towards healthy eating (odds ratio [OR] = 0.41; 95% CI 0.17-0.99) and family practices (OR = 0.48; 95% CI 0.23-1.00). We provide evidence that higher food budgets were associated with higher diet diversity, but not with improved diet quality. Attitude, but not knowledge, was linked to better diet quality. Future studies should focus on the specific contribution of aspirational, situational and behavioural factors in directing increased diversity towards favourable eating habits.

Knowledge, attitude, and practice of cardiac rehabilitation among patients after coronary artery stenting

Stent implantation effectively relieves coronary artery disease (CAD), and post-surgery cardiac rehabilitation is essential for prognosis. This study aimed to investigate the knowledge, attitude, and practice (KAP) of patients undergoing coronary artery stenting regarding cardiac rehabilitation. Conducted in multiple hospitals from December 2023 to January 2024, a self-administered questionnaire collected demographic information and KAP scores. A total of 452 valid subjects were included, with 262 participating in cardiac rehabilitation. The average age was 56.76 ± 12.97 years, with 57.52% male and 72.35% urban residents. Mean KAP scores were 14.63 ± 4.70 (knowledge), 37.50 ± 4.15 (attitude), and 30.96 ± 4.49 (practice). Positive correlations were found between KAP scores (r = 0.378-0.474, P < 0.001). Urban residence, angina, and myocardial infarction diagnoses were positively associated with knowledge (OR = 1.881-3.192, P < 0.05). Conversely, medical insurance, continued drinking post-implantation, and other underlying diseases were negatively associated (OR = 0.193-0.592, P < 0.05). Myocardial infarction diagnosis (OR = 2.059, P = 0.026) and health education (OR = 1.830, P = 0.018) positively influenced attitudes. Medical insurance was associated with practice (OR = 4.567, P = 0.028). Patients showed moderate knowledge and positive attitudes towards cardiac rehabilitation, highlighting the need for educational interventions for rural residents and individuals who did not initiate rehabilitation.

Development and psychometric evaluation of nutrigenomics and personalized nutrition-related knowledge, attitude, and behavior questionnaire in dietetic students and professionals

This study aimed to develop and test the psychometric properties of a questionnaire assessing knowledge, attitudes, and behaviors (KAB) related to nutrigenomics and personalized nutrition (PN) in dietetic students and professionals in India. A literature review, six focus group discussions (n = 37), and nine in-depth interviews guided initial item generation. The face, item, and scale content validity indices were calculated and a cross-sectional sample (n = 297) examined the item difficulty (IDI), item discrimination (DI), and internal consistency. Test-retest reliability was estimated in a sub-sample (n = 64) and confirmatory factor analysis method (CFA) using model fit indices - factor loadings, Tucker Lewis Fit Index, and Root Mean Square Error of Approximation established construct validity. The IDI ranged from 0.60 to 0.72 and the mean Cronbach α was 0.82. The CFA results presented four constructs - 1) knowledge and understanding of nutrigenomics, 2) attitude, and willingness to learn nutrigenomics, 3) behaviors toward gene-based dietary advice, 4) training and confidence to practice PN. The intraclass correlation coefficients for knowledge, attitude, behavior, and training domains were 0.74, 0.83, 0.72, and 0.81. The psychometric evaluation indicated that the 45-item KAB_PN is a valid and reliable instrument to assess students' and dietitians' knowledge and perspectives toward nutrigenomics and PN.

The Knowledge, Attitudes, and Practices of Healthy Eating Questionnaire: a pilot validation study in Chinese families

Introduction

Identifying the knowledge, attitudes, and practices (KAP) gaps of healthy eating can inform the design of effective interventions. This study aimed to test the validity and psychometric properties of a KAP of Healthy Eating Questionnaire (KAP-HEQ) tailored to the Chinese culture.

Methods

The dimensions and potential items of each KAP scale were identified from published KAP and health literacy questionnaires, which were supplemented by the findings of a previous qualitative healthy eating study. Content validity of the KAP-HEQ was evaluated by eight experts and eight Chinese parent-adolescent dyads in Hong Kong through content validity ratio (CVR), content validity index (CVI), and qualitative feedback. The feasibility, construct validity, reliability, and sensitivity of the KAP-HEQ were evaluated in this pilot study among 60 adolescent-parent dyads (120 persons) through an online survey. The first 30 dyads who completed the KAP-HEQ were invited to repeat the KAP-HEQ 2 weeks later to assess the test-retest reliability.

Results

The final 44-item KAP-HEQ was completed in 10-15 min by both adolescents and their adult parents. The CVR ranged from -0.38 to 1, and the CVI ranged from 0.56 to 1. Over 80% of the items achieved convergent validity (a significantly positive correlation with its hypothesized scale) and discriminant validity (a higher correlation with its hypothesized scale than with the other two scales). Cronbach's alpha for the internal consistency of the Overall, Attitude, and Practice scales was >0.7, while that of the Knowledge scale was 0.54. The intraclass correlation coefficient (ICC) on test-retest reliability of the Overall and individual scales were all >0.75 except that of the Knowledge scale (ICC = 0.58). The significant differences in KAP scale scores with small to large effect sizes were found between known groups as hypothesized, except the Attitude score between groups by household income, which supported the sensitivity of the KAP-HEQ.

Conclusion

The KAP-HEQ has shown good validity, reliability, and sensitivity among Chinese adolescents and adults, which can be applied to evaluate KAP status and gaps to inform the design and assess the effectiveness of healthy eating interventions.

Reliability and validity of a questionnaire measuring knowledge, attitude and practice regarding "oil, salt and sugar" among canteen staff

Excessive intake of oil, salt and sugar is closely associated with the prevalence of non-communicable chronic diseases (NCDs). Canteen staff's knowledge, attitude and practice (KAP) about oil, salt and sugar directly affect the content in dishes and the consumers' intake. However, no valid questionnaire is used to assess KAP among canteen staff about the "oil, salt and sugar". Therefore, the present study aimed to establish and validate a questionnaire to evaluate the KAP of canteen staff about the "oil, salt and sugar". This cross-sectional study was conducted among canteen staff randomly selected from three college canteens. Participants completed the questionnaire and retested it two weeks later. Internal and test-retest reliability were assessed using Cronbach's α and Pearson correlation coefficients, respectively. Validity was assessed using the exploratory factor analysis. 100 participants finished the questionnaire, of which 66% were females with a mean age of 40.3 ± 10.5 years. The Cronbach's α coefficients of the total questionnaire and Knowledge, Attitude and Practice dimensions were 0.822, 0.830, 0.752 and 0.700, respectively. The test-retest reliability coefficient was 0.968. In exploratory factor analysis, nine common factors were extracted, with 26 items, and the cumulative contribution rate was 70.9%. The questionnaire had a satisfactory property for measuring the KAP of the "oil, salt and sugar" among canteen staff in China.

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.

Attitude towards the Promotion of Healthy Eating among Secondary School Teachers—Construction and Validation of a Questionnaire

Health promotion activities in secondary schools are scarce and have little involvement of the teaching staff. Most often, activities are developed from the curriculum that appears in school materials, with little capacity for adaptation and innovation. The aim of this study was to construct and validate a tool to find out teachers’ attitudes towards activities to promote healthy eating in secondary schools. For this purpose, a descriptive study was conducted. The total sample of the study consisted of 200 teachers from secondary schools. Internal consistency was determined by Cronbach’s alpha coefficient globally and by dimension, and with the corrected item–test correlation. The construct validity of the questionnaire was assessed by means of an exploratory factor analysis, for which the principal components method with Varimax rotation was used. A Likert-type scale with nine items and four response options about attitude was designed. The exploratory factor analysis showed a nine-factor solution, of which two had eigenvalues greater than 1. These two factors explained 63.4% of the variance. The Cronbach’s alpha internal consistency index obtained for the global scale was 0.81, and 0.75 and 0.85 for each component. The results obtained with this structure confirmed an adequate reliability and validity of the questionnaire.

Impact of screen time during COVID-19 on eating habits, physical activity, sleep, and depression symptoms: A cross-sectional study in Indian adolescents

OBJECTIVE

This study attempted to address the limited knowledge regarding the impact of screen time (ST) on lifestyle behaviors in Indian adolescents during the ongoing COVID-19 pandemic. The objectives were to 1) evaluate frequency and duration of using screens, and screen addiction behaviors in 10-15 years old adolescents in Mumbai during the COVID-19 pandemic and 2) examine the association of ST with lifestyle behaviors- eating habits, snacking patterns, physical activity (PA) levels, sleep quality and depression symptoms.

METHODS

An online survey was completed between January and March 2021. Eating habits, snacking patterns, time spent in different screen-based activities, and screen addiction behaviors were reported. The PA levels, sleep quality, and depression symptoms were evaluated using the Physical Activity Questionnaire for Children/Adolescents (PAQ C/A), Pittsburg Sleep Quality Index (PSQI), and Patient Health Questionnaire-2 (PHQ-2) respectively. Multiple linear regression analyses were performed to determine the impact of ST on lifestyle behaviors.

RESULTS

Adolescents (n = 1298, Mage 13.2(1.1), 53.3% boys) reported the mean weekday and weekend ST as 442.3 (201.5) minutes/d and 379.9 (178.2) minutes/d respectively. Overall, 33.4% spent > 6hours/d for studying or doing homework, 65.4% used social networking sites for at least 2-3 hours/d, and 70.7% agreed that ST had taken up the majority of their leisure time. Only 12% engaged in moderate to vigorous PA (PAQ C/A scores <2). More than half (52.5%) reported PSQI >5 indicating poor sleep quality and 8.6% scored ≥ 3 on PHQ-2 to suggest a risk of depression. A higher ST was associated with lower PA and increased sleep problems and a greater screen addiction was inversely associated with the eating habit, PA, and sleep-related variables.

CONCLUSION

The study draws attention to a high prevalence of excess ST and its impact on eating habits, PA levels, and sleep quality in Indian adolescents during the COVID-19 pandemic. Targeted health promotion interventions that encourage judicious use of screens for education and entertainment and emphasize the adverse health effects of excess ST are required.

Independent and combined influences of physical activity, screen time, and sleep quality on adiposity indicators in Indian adolescents

BACKGROUND

Inadequate physical activity (PA), excess screen time (ST), and sub-optimal sleep quality tend to co-occur during adolescence. Yet, little is known about the associations of these behaviors as a cluster with adiposity indicators in Indian adolescents. This study aimed to evaluate the independent and combined influences of PA, ST, and sleep quality on body mass index (BMI) and waist to height ratio (WHtR) in 10-15 years old adolescents in Mumbai, India. A secondary aim was to explore if these influences vary between sexes.

METHODS

Cross-sectional study. Adolescents (n = 772, mean age 13.2 (1.4) years) reported frequency and duration of moderate to vigorous PA (MVPA) and time spent using screens on a previously validated instrument. Sleep quality was estimated using the Pittsburg Sleep Quality Index (PSQI). Weight, height, and waist circumference were measured. Mixed effect logistic regression analyses were performed to explore associations between adiposity indicators (BMI z scores > +1SD and WHtR > 0.5) and unhealthy behaviors (PA < 60 min/d, ST > 120 min/d and PSQI scores > 5), stratified by sex.

RESULTS

The combined prevalence of overweight and obesity was 38.3%. Overall, 62.0 and 85.0% reported MVPA< 60 min/d and ST > 120 min/d respectively. Girls reported higher ST (218.21 (69.01) min/d) as compared to boys (165.3 (101.22) min/d, p < 0.001). Clustering of low PA and excess ST was observed in 69.2% and of all three unhealthy behaviors in 18.8%. Among girls, MVPA < 60 min/d (OR = 1.78, 95% CI 1.54-1.92, p < 0.001) and PSQI scores > 5 (OR = 2.01, 95% CI 1.78-2.25, p < 0.001) predicted increased BMI. The odds of overweight/obesity were 2.10 times higher in boys reporting low PA and 4.13 times higher in those with low PA+ ST > 120 min/d. Clustering of all three unhealthy behaviors increased prevalence of obesity in both sexes.

CONCLUSIONS

The results indicated a co-existence of multiple unhealthy lifestyle factors of obesity and that clustering of these behaviors can further aggravate obesity risk as compared to their independent effects. Integrated interventions that leverage the cumulative benefits of being active, less sedentary and sufficient sleep are warranted to facilitate greater improvements in obesity risk behaviors.

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.
