Impact of a Nutrition Knowledge Intervention on Knowledge and Food Behaviour of Women Within a Rural Community

INTRODUCTION

The influence of women in shaping household dietary habits is undeniable, with their maternal nutritional knowledge significantly impacting the overall well-being of their families. The study objective was to evaluate the impact of maternal nutritional knowledge on household dietary habits, emphasising the improvement in women's nutrition knowledge and food-related behaviours.

PURPOSE

This study aimed to assess the immediate and long-term effects of a nutrition education intervention on the nutrition knowledge and food-related behaviours of women.

METHODOLOGY

A quasi-experimental research design was employed to assess the effects of a Nutrition Education Programme (NEP) on female caregivers' nutrition knowledge and food-related behaviours. This study followed a four-phase approach: baseline survey, programme formulation, implementation and evaluation. Data were collected at various stages of this study using two measurement tools: a Dietary Diversity Questionnaire and a Nutrition Knowledge Questionnaire.

RESULTS

Statistical analysis was performed to answer the research questions and to test the null hypotheses at a significance level of 0.05. The intervention positively affected nutrition knowledge, with the mean percentage increasing from 49.1% to 63.7% and reaching 64.4% at follow-up, indicating long-term knowledge retention. The findings of this study suggest a positive shift towards increased consumption of nutrient-rich food groups. There were significant improvements in the food groups' consumption of the meat group (7.15 ± 2.35), eggs (1 ± 0), dairy (3.76 ± 1.19), cereal (8.78 ± 2.09), legumes (2.86 ± 0.95) and fats and oils (2.12 ± 0.55). Additionally, the variety of food groups consumed significantly improved (p = 0.012) post-intervention, with an increasing trend in the consumption of a variety of food groups (7-9).

RECOMMENDATION

Tailored nutrition education (NE) programs, in conjunction with addressing socioeconomic barriers positively impact nutritional behaviours, promote healthier food consumption patterns and assist in long-term knowledge retention in disadvantaged communities.

The effect of therapeutic education program on hypertensive Tunisian patients' knowledge: a randomized controlled trial

Background

Hypertension is a prevalent non-communicable disease and unequivocally one of the most serious health threats of the twenty-first century. The prevention of both immediate and long-term consequences depends on ongoing therapeutic education.

Aims

To assess Tunisian hypertensive patients' knowledge of hypertension and then evaluate the impact of an educational program on knowledge among this population.

Methods

A randomized controlled trial was carried out among 639 hypertensive patients in Tunisia. The control group received only basic medical care, while the experimental group acquired additionally an educational program. The data collection tool was a questionnaire that included an information sheet and the Hypertension Knowledge Level Scale (HK-LS).

Results

Before to the implementation of the program, only 12.1% of the participants had a good level of knowledge about hypertension (12.8% for the experimental group, vs. 10.5% for the control group, P=0.57). Following the program's deployment, the rate of good level of knowledge became 63.6% for the experimental group vs. 11.4% for the control group, P<0.001). The results revealed that the experimental group showed a significant amelioration in the total score of the HK-LS: from 58.49 to 76.94%, P<0.0001. In contrast, no significant amelioration was noted in the control group. Concerning the six dimensions of the scale, the amelioration in the experimental group was observed in all dimensions, except the treatment dimension.

Conclusion

Overall, the findings indicated low levels of knowledge about hypertension. This kind of approach proved an effective improvement in disease-related knowledge and may be essential for hypertension management.

Determinants of sodium intake knowledge and attitude: a cross-national analysis of socio-economic and health factors

OBJECTIVE

The aim of this study is to conduct a comparative analysis across nations to: (1) identify the determinants influencing knowledge and attitudes related to sodium (Na) intake and (2) to analyse the association between knowledge and attitudes related to Na intake.

DESIGN

We utilised a secondary data from a cross-sectional study that was conducted across seven nations. Structural equation modelling (SEM) was utilised to assess the impact of socio-economic and health-related predictors on knowledge and attitudes pertaining to Na intake and further to investigate the relationship between knowledge and attitude.

SETTING

Indonesia, Brazil, Thailand, Japan, France, the UK and the USA.

PARTICIPANTS

7090 participants aged 15 years and above were included in the study.

RESULTS

SEM analysis showed a strong association between knowledge about Na intake and related attitude across all countries, particularly in the UK (2·65, 95 % CI 1·48-3·82), France (2·62, 1·45-3·79) and the USA (1·97, 1·21-2·73). In Brazil, Japan and France, individuals or family members having certain health conditions such as raised blood pressure, heart diseases, strokes or other diseases exhibited a positive attitude towards reducing Na intake. Conversely, socio-economic factors like education and income demonstrated the complexity of influences on knowledge and attitudes about Na intake.

CONCLUSION

The study underscores the need for tailored public health interventions to reduce excessive Na consumption, considering the diverse cultural, social and economic factors. It highlights the complex determinants of knowledge and attitudes towards Na intake, calling for further research in varied populations.

An educational intervention for improving knowledge, attitude, and practice of dietary salt intake among individuals with hypertension in public sector secondary care facilities, Agra, India, 2021

We conducted a pre-post intervention study to determine knowledge, attitude, and practice toward dietary salt intake before, immediately, and 1-month after nurse-led one-on-one counseling. We purposively selected three public health facilities in Agra, India, and enrolled all eligible hypertensive patients aged 18-60 under treatment for ≥6 months. Of the 153 patients at the 1-month follow-up, counseling improved knowledge (4% vs. 42%, p < .001), a greater prioritization of a low salt diet (34% vs. 52%, p < .001), and practice of adding less salt to the dough (48% to 41%, p < .001). The counseling intervention improved knowledge, attitude, and practice toward dietary salt intake.

Impact of a Nutrition Education Intervention on Salt/Sodium Related Knowledge, Attitude, and Practice of University Students

Background

Salt reduction strategies help reduce the risk of cardiovascular diseases (CVDs) by reducing high blood pressure. This study aimed to assess salt related knowledge, attitude, and practices (KAP) before and after administering an evidence-based nutrition education workshop.

Methods

Ninety non-medical university students were recruited to investigate KAP related to dietary salt intake. The KAP components were assessed before, immediately after, and 4-weeks after administering an evidence-based educational workshop and leaflet.

Results

Knowledge and attitudes related to salt improved significantly immediately post-intervention but were not fully retained after 4-weeks. Five of the 13 evaluated practices improved after 4-weeks: trying to buy low-salt foods increased from 10 to 19% (P = 0.022), rarely adding salt to food during cooking increased from 5 to 16% (P = 0.019), rarely adding salt to food at the table increased from 29 to 42% (P = 0.011), tried to reduce salt intake increased from 26 to 41% (P = 0.014), and tried to use spices to reduce salt increased from 31 to 45% (P = 0.044).

Conclusions

The educational intervention had a positive impact on salt-related knowledge, attitudes, and practices, but the effect was not fully retained on the long-term. Periodic educational interventions should be considered to refresh knowledge and reinforce practices.

Strengthening Knowledge to Practice on Effective Salt Reduction Interventions in Low- and Middle-Income Countries

PURPOSE OF REVIEW

The objective of this review was to consolidate available published information on the implementation and evaluation of salt reduction interventions in low- and middle-income countries (LMICs).

RECENT FINDINGS

The Science of Salt database (made up of studies identified in a weekly Medline search) was used to retrieve articles related to the implementation of salt reduction interventions from June 2013 to February 2020. Studies that measured the effects of the interventions in LMICs, based on four outcome measures-salt intake; sodium levels in foods; knowledge, attitudes, and behaviours (KABs) towards salt; and blood pressure-were included. Results were summarised overall and according to subgroups of intervention type, duration, sample size, country's income class, and regional classification. The review identified 32 studies, representing 13 upper middle-income and four lower middle-income countries. The main salt reduction interventions were education, food reformulation, and salt substitution; and many interventions were multi-faceted. More studies reported a positive effect of the interventions (decreased salt intake (12/17); lower sodium levels in foods or compliance with agreed targets (6/6); improved KAB (17/19); and decreased blood pressure (10/14)) than a null effect, and no study reported a negative effect of the intervention. However, many studies were of small scale and targeted specific groups, and none was from low-income countries. Consumer education, food reformulation, and salt substitution, either alone or in combination, were effective in their target populations. Supporting scale-up of salt reduction interventions in LMICs is essential to cover broader populations and to increase their public health impact.
