Evaluation of Nutrition and Physical Activity Knowledge, Attitudes, Self Efficacy and Behaviors in Teachers and Children after Implementation of the “Healthy Active Kids” Online Program in Australian Elementary Schools

The aims were to examine change in nutrition and physical activity knowledge, self efficacy and attitudes in a cohort of 23 teachers and 304 year 5 and 6 children after the “Healthy Active Kids” online program and to assess any behavioral change in children’s self reported nutrition and physical activity behaviors and investigate the predictors of nutrition knowledge gain in teachers and children. Results found significant (p < 0.0001) increases in teacher and student knowledge of the five food groups;key nutrients provided by each food group, The Australian Guide to Healthy Eating;food labelling laws, identification of common names for fats, sugars and salts on food labels, food proportions on the Healthy Food Plate and the level and percentage of water in the human body and human brain. Teacher attitudes towards the importance of nutrition and diet and self efficacy related to teaching nutrition in class improved (p < 0.01). The final regression model for predictors of the dependent variable, knowledge gain in students was R = 0.53, Adjusted R square = 0.28 (F = 4.76, p < 0.01) indicating that 28% of the variation in knowledge gain was predicted by the negative (low) Time 1 knowledge. Changes to eating habits reported by children were “drinking more water each day” (89.1%) and “eating foods from the five food groups each day” (76.2%);“sharing information about food labels with your family” (52.4%);“reading food labels when you go shopping” (50.0%);“changing what is on your dinner plate each night” (44.2%);“vegetables that you eat now that you didn’t eat before” (42.1%) and “fruits that you eat now” (39%). Results suggest that the development of basic nutrition knowledge is still very important for both teachers and students, but that other factors such as self efficacy, empowerment and skill development also contribute to nutrition behavior change in children.

A Comparison of the Sexual Knowledge, Attitudes, and Behaviors of Korean College Students Studying in Korea and in the United States

The number of Korean students enrolling in universities overseas is rapidly growing. However, these populations are underrepresented in sexuality related research, despite the possibility of sexually risky behavior in overseas university students. We examined the sexual knowledge, attitudes, and behaviors of university students in Korea and studying in the United States. Data were collected—131 Korean students in Korea and in the US using a web-based self-report questionnaire system. Students in the US showed greater total sexual knowledge than students studied in Korea. There were differences in the sexual knowledge, attitude and behaviors according to general characteristics between both groups. Although students in the USA had a higher level of sexual knowledge, both students in the USA and in Korea had a low level of sexual knowledge overall.

Effect of a Nutrition Education Intervention on Food Safety Knowledge, Attitudes and Practices of Mothers of Children under 5 Years in the Peri-Urban Areas of Bobo-Dioulasso: Before and after Study

Background: This study assessed the effect of a nutrition education intervention. This intervention aimed to improve the knowledge, attitudes, and practices of mothers on food safety in the peri-urban areas of Bobo-Dioulasso in Burkina Faso. Methods: A total of 243 mothers of children under 5 years in the peri-urban of Bobo-Dioulasso were administered the FAO questionnaire for food safety knowledge, attitudes, and practices assessment during two cross-sectional surveys, before and after the intervention, in January and October 2017. The intervention included two components consisting of a theoretical phase (counselling and discussion) and cooking demonstrations implemented for ten months. To account for the before-and-after design of the study, the McNemar’s test was used to assess the effect of the intervention on food safety KAP of mothers of children under 5 years. Results: The mean age of mothers was 29 ± 6.2 years and 50.6% of them were between 20 and 29 years old. One for knowledge (cooking thoroughly with, p-value = 0.0001) and another for attitudes (perceived benefits of reheating leftovers before eating them, p-value = 0.0001), significantly increased after the intervention. In terms of food safety practices, all the indicators (cleaning of dirty surfaces, plates and utensils and storage of perishable foods) significantly increased (all p = 0.0001 Conclusion: This study provided some evidence of an effective nutrition education intervention for improving maternal KAP on food safety for their child’s feeding.

Knowledge, Attitudes, and Practices Relating to Food and Nutrition among Pregnant Women Attending Antenatal Clinics at Menontin Hospital (Benin)

Introduction: Pregnancy is a critical period during which environmental factors such as nutrition can affect the optimal development of the fetus. This study aims to evaluate the knowledge, attitudes, and practices in food and nutrition among pregnant women in antenatal consultation at Menontin Hospital in 2021. Methods: This was a cross-sectional, descriptive study including 96 pregnant women at Menontin Hospital in Cotonou. Variables including socio-anthropological data, level of knowledge of nutritional requirements and their consequences on malnutrition, and description of physical activity practices were collected using a questionnaire and data on pregnant women’s dietary practices, macronutrient consumption, and fruit and vegetable consumption were documented using a food frequency questionnaire. Results: The majority of pregnant women (88%) were unaware of their nutrient needs during pregnancy. Only 49.6% of them took at least three meals and two snacks a day, and 45% practiced less than 30 minutes of physical activity per day. The consumption of carbohydrates, proteins, and lipids were respectively in the proportions of 36.5%, 50%, and 38.5%. It was also found that 48% of pregnant women did not consume fruits and vegetables daily. Conclusion: The pregnant women followed in the Mènontin area hospital had a low level of knowledge in terms of food and nutrition during pregnancy. Consequently, their attitudes and practices were unfavorable to good nutrition for both the mother and the child.

Knowledge, Attitudes and Practices of Caregivers of Children 0 - 23 Months in Eastern and Central Uganda

Introduction: Appropriate feeding and consequently good nutritional status of young children largely depends on their caregivers. Aim: The current study aimed at assessing maternal/caregivers’ current knowledge, attitudes, practices, and beliefs regarding different aspects of infant and young child feeding in Eastern and Central Uganda. Methodology: A cross-sectional survey design with mixed methods employing both qualitative and quantitative methods was used for data collection. Results: The study participants included 556 caregivers and 572 children. Results indicate that most caregivers (77%) were knowledgeable about key infant and young child feeding practices such as breastfeeding, complementary feeding and meal frequency. However, culture and economic hardships were a major barrier to the applicability of this knowledge. Nearly all (98%) children were ever breastfed with 41% having been initiated on breast milk in the first hour after birth and 68% of all the children below 6 months exclusively breastfed. Three percent of the children aged 6 - 23 months were classified as having either Moderate (2%) or Severe (1%) Acute malnutrition. The median birth weight was 3.2 Kgs with nine percent of the children classified as underweight at birth. The majority (78%) of the children consumed foods from at least four food groups however only 44% consumed heme-rich animal flesh food such as meat, poultry, organ meats and fish, 29% consumed milk and milk products while only 11% consumed eggs. The barriers to improved nutritional status and health-seeking behaviour in children from both regions were largely similar. Some of these included cultural practices which prohibit children from eating certain foods and lack of drugs in the health facilities. Lack of male involvement was a key barrier to health-seeking behaviour and the nutritional well-being of children. Males were, however, more knowledgeable about the key childcare practices that are critical to positive outcomes because they listen to radios, have access to social media and usually congregate at bars where this information is disseminated and exchanged. Conclusion: There should be continuous sensitization of mothers on the benefits of breastfeeding with special focus on early initiation and exclusive breastfeeding as well as child feeding practices during illness. To increase protein intake in children 6 - 23 months, interventions aimed at increasing consumption of these vital nutrients such as promotion of nutrition-sensitive agricultural enterprises like rearing of small livestock and chickens should be emphasized. Consumption of these foods is critical, especially during pregnancy and infancy. Finally, male involvement in maternal and child feeding should be encouraged.

Nutritional Knowledge and Behavior of Professional Athletes in Khorramabad

Today it is proved that the lack of adequate nutritional knowledge leads to problems such as obesity, overweight and increased cardiovascular diseases. However, many obstacles such as poor financial support, lack of time and poor nutritional knowledge can influence achievement of optimal nutrition which is proportional to the level of the athlete＇s physical activity. The purpose of this study was to determine the level of nutritional knowledge and dietary behavior of athletes in Khorramabad in 2013. Professional athletes of Khorramabad, Iran, with more than one year of regular exercise and at least one course participating in national championships competitions were studied in this cross-sectional, descriptive-analytic study. The samples included 247 athletes aged 17-29 years. Their nutritional knowledge and behavior were measured by the nutritional knowledge and behavior inventory. Results： The results showed a significant difference in nutritional knowledge of athletes by gender and educational level; female athletes have higher nutritional knowledge than male athletes. A gender-dependent difference was found in nutritional behavior; despite their higher nutritional knowledge, female athletes have weaker nutritional behavior than male athletes. However, no significant correlation was found between BMI and nutritional knowledge and behavior of the athletes. Moreover, findings showed that nutritional knowledge and behavior could be significantly different in various sports.
