A Nutrition Education Intervention to Increase Consumption of Pulses Showed Improved Nutritional Status of Adolescent Girls in Halaba Special District, Southern Ethiopia

The Effect of an Educational Intervention Based on the Health Belief Model (HBM) on Nutritional Performance Related to Gastric Cancer in Rural Women in Northern Regions of Iran

Gastric cancer is a common cause of cancer death in the world. This study examined 120 rural women. The educational program included four sessions for each group based on the health belief model. The mean age of the women was 34.51 ± 9.16. The mean score of the perceived barriers significantly decreased in the experimental group (11.08 ± 0.37) compared to the control group (14.92 ± 0.42) (P < .001), and the mean score of knowledge, performance and HBM constructs, increased significantly 2 months after the education (P < .001).It is recommended that educational interventions be designed by HBM to improve nutritional behaviors related to GC in the female population.

Evaluation of effectiveness of school-based nutrition education in improving the consumption of pulses-based food among female adolescents in Northwest Ethiopia: a cluster randomized controlled trial

BACKGROUND

Protein undernutrition is a prevalent health problem in Ethiopia severely affecting the reproductive outcome of women. This is mainly because of inadequate consumption of protein due to the high cost of animal-origin food and the lack of knowledge about the benefits and the methods of preparation of pulses-based foods. Therefore, this trial was conducted to evaluate the effectiveness of nutrition education in improving the consumption of pulses-based foods among female adolescents.

METHODS

A two-arm pragmatic cluster randomized controlled trial was conducted among female adolescents in Northwest Ethiopia. Clusters were schools assigned into intervention and control groups by cluster randomization. The trial participants were female adolescents. The intervention was pulses-based nutrition education, and the comparator was the usual dietary practice of adolescent girls. The education was delivered over four weeks on a 45-60 min session per week basis. The primary outcome of the intervention was pulses-based food consumption, and the secondary outcomes were knowledge and attitude about pulses food. Data on the outcome and the confounding variables were collected at baseline and end-line of the intervention. The analysis was based on intention-to-treat analysis, and a log-binomial logistic regression model was fitted to the data to calculate relative risk with the corresponding p value adjusted for baseline characteristics. The intervention was considered effective when the p value was < 0.05.

RESULTS

A total of 269 intervention and 278 control participants from the four clusters completed the trial making response rates of 92.1% and 95.2%, respectively. The pulses-based nutrition education enabled participants in the intervention group to maintain their pulses-based food consumption state, while participants in the control group significantly reduced their consumption by about threefold [ARR; 95% CI 2.99 (1.87, 4.79)] from harvesting to non-harvesting season. The consumption of pulses-based food was higher by 16% among the intervention participants as compared to the control participants [ARD; 95% CI 0.16 (0.10, 0.21)].

CONCLUSION

Pulses-based nutrition education is effective in improving the consumption of pulses-based food among female adolescents. Therefore, policies and strategies are required to integrate this intervention in the school nutrition program.

Feasibility and impact of school-based nutrition education interventions on the diets of adolescent girls in Ethiopia: a non-masked, cluster-randomised, controlled trial

BACKGROUND

Adolescence is a critical period of physical and psychological development, especially for girls, because poor nutrition can affect their wellbeing as well as that of their children. We aimed to assess the feasibility and impact of a package of nutrition education interventions delivered through public primary schools on the diets of adolescent girls in Ethiopia.

METHODS

In this non-masked, cluster-randomised, controlled trial, primary schools (clusters) in the Southern Nations, Nationalities, and People's Region and Somali region of Ethiopia were randomly allocated to the intervention group (nutrition information provided during flag ceremonies, classroom lessons, school club meetings, peer group mentoring, BMI measurement and counselling, and parent-teacher meetings) or the control group (standard academic curriculum on health and nutrition) by use of computer-generated pseudo-random numbers. Duration of the school-based interventions was 4 months, and the key messages were related to dietary diversity (eating a variety of foods), energy adequacy (eating breakfast and healthy snacks), and healthy food choices (avoiding junk foods). Adolescent girls were eligible for participation if aged 10-14 years and enrolled in grades 4-8 in a study school. Data were collected with two independent cross-sectional surveys: baseline before the start of implementation and endline 1·5 years later. The primary outcome of impact was dietary diversity score, defined as the number of food groups (out of ten) consumed over the previous 24 h using a list-based method, and minimum dietary diversity, defined as the proportion of girls who consumed foods from at least five of the ten food groups, in the intention-to-treat population. We also assessed intervention exposure as a measure of feasibility. We estimated intervention effects using linear regression models for mean differences at endline, with SEs clustered at the school level, and controlled for adolescent age, region, household food security, and wealth. The trial is registered with ClinicalTrials.Gov, NCT04121559, and is complete.

FINDINGS

27 primary schools were randomly allocated to the intervention group and 27 to the control group. Between March 22 and April 29, 2021, 536 adolescent girls participated in the endline survey (270 in the intervention group and 266 in the control group), with median age of 13·3 years (IQR 12·1-14·0). At endline, the dietary diversity score was 5·37 (SD 1·66) food groups in the intervention group and 3·98 (1·43) food groups in the control group (adjusted mean difference 1·33, 95% CI 0·90-1·75, p<0·0001). Increased minimum dietary diversity was also associated with the intervention (182 [67%] of 270 in the intervention group vs 76 [29%] of 266 in the control group; adjusted odds ratio 5·37 [95% CI 3·04-9·50], p<0·0001). 256 (95%) of 270 adolescent girls in the intervention group were exposed to at least one of the five in-school intervention components.

INTERPRETATION

Integrating nutrition interventions into primary schools in Ethiopia was feasible and increased dietary diversity incrementally among adolescent girls, but could be limited in changing other food choice behaviours, such as junk food consumption, based on nutrition education alone.

Dietary practice and nutritional status and the respective effect of pulses-based nutrition education among adolescent girls in Northwest Ethiopia: a cluster randomized controlled trial

Background

Thinness and stunting are the most severe public health problems among adolescent girls in Ethiopia. An inadequate intake of protein-source foods is the most critical cause, mainly due to the non-affordability of animal-origin foods. However, research into what extent improving pulses-based food consumption could contribute to decreasing the magnitude of protein-energy undernutrition is limited.

Objective

This trial aimed to evaluate the effectiveness of pulses-based nutrition education in reducing the proportion of thinness among adolescent girls.

Methods

A two-arm cluster randomized controlled trial was conducted among adolescent girls in Northwest Ethiopia from December 2021 to June 2022. A total of 602 adolescent girls from four schools were enrolled in the trial. Schools were assigned to intervention and control groups using the stratified cluster randomization method. Pulses-based nutrition education was the intervention, whereas the usual dietary practice of adolescent girls was the comparator. The education was delivered over 4 weeks on a 45-60-min session per week basis. Thinness was the primary outcome of the trial, measured by anthropometry. An intention-to-treat analysis method was used. A log-binomial regression model was fitted to the data. Relative risk with the respective confidence interval and value of p was calculated. A value of p < 0.05 was used to declare statistical significance. Stata 16 software was used for the analysis.

Results

About 89.37% of the participants in the intervention group and 92.36% in the control group completed the trial. The pulses-based nutrition education intervention did not show a significant difference in reducing the proportion of thinness among the participants in the intervention group compared to the participants in the control group even though a significant difference was observed in terms of the consumption of pulses-based food.

Conclusion

The present trial was statistically non-significant in reducing thinness among adolescent girls. Similar studies that utilize objective methods for ascertaining pulses-based food consumption need to be conducted.Clinical trial registration: https://pactr.samrc.ac.za/Search.aspx, the trial was registered in the Pan African Clinical Trials Registry (PACTR202111605102515) on November 12, 2021.

Assessment of high school learners' familiarity with nutrition education principles

BACKGROUND/OBJECTIVES

The objective of the study was to assess adolescent learners' nutritional knowledge to suggest early intervention strategies that address knowledge deficiency gaps that have a negative impact on personal health and productivity.

SUBJECTS/METHODS

A cross-sectional survey design was used in the study. One circuit was purposively selected from Pinetown District, KZN, South Africa. A representative sample of 108 learners was randomly selected from 7 of the 8 schools in the district to complete the investigator administered questionnaire between July and August 2017.

RESULTS

Although the majority of learners were familiar with the nutrition education principles, a large proportion lacked the knowledge of essential nutrition and were in support of the incorporation of various strategies to promote nutrition education. Friedman test revealed significant differences, χ² (3) = 192.4, p < 0.001, between the mean rank scores of familiarity to different nutrition principles. Relative to other principles, balanced diet and food groups were the most critical issues. The overall mean of 3.7 for learners' priority level on nutrition education principles indicated the learners' view that knowledge of all principles was necessary for the attainment of a healthy lifestyle.

CONCLUSIONS

Many learners were not familiar with nutrition education principles. Hence this paper becomes very critical as it communicates the information to the community and suggests various nutrition education intervention strategies that have to be put in place in the school system to impart the necessary knowledge and skills that promote a long-term healthy lifestyle for the learners.
