ABSTRACT

Background and Objective: Access to a nutritious mid-day meal is important for the overall well being and academic performance of school children. This cross-sectional study evaluated the nutrient content and percentage of Recommended Daily Intake (RDI) met by pupils who consumed home-packed lunch. Methodology: Two primary schools were purposively selected from a University town in South East of Nigeria. A total of 200 pupils and their mothers participated in the study. Questionnaire was used to obtain background information and socio-economic characteristics of the parents of the pupils. Home-packed lunch of each pupil was weighed for 3 days and food composition table used to calculate the mean nutrient content of the meals of all the children. The percentage of RDI met by the pupils was also calculated. Results: The results revealed that 90.2% of the pupils had breakfast at home and 78.3% went to school with home-packed lunch such as, jollof rice (21%), indomie noodles/spaghetti (17.5%), biscuits (28.7%) and pastries (14.7%). About 15% of the pupils bought foods from hawkers around the school compound. The pupils who consumed home-packed lunch met 1/2 of their carbohydrate, vitamin B and zinc, 1/3 of protein, iron and potassium, 1/20 vitamin A, 1/22 of calcium, 1/5 of vitamin C RDI. Conclusion: There is need for adequate nutritional counseling of parents/guardians on choice and combination of foods for school lunch that would meet the recommended 1/3 of the RDI for all nutrients needed for optimal growth, development and academic performance of school children.

INTRODUCTION

Adequate nutrition is paramount for optimal growth and development as well as in reducing risks associated with both immediate and long-term health problems in school children. Nutritional and health status have influences on a child’s learning ability and school performance. Access to a nutritious mid-day meal is crucial in maintaining good nutritional status as well as the overall well being and cognitive development of a school child. According to UNICEF1, hungry children may have difficulty in concentrating or performing academic activities even when healthy and well-nourished. Meals provided during school hours alleviate short term hunger, increase attention span, facilitate learning and obviate the need for children to leave school in search of food2. School-age children are nutritionally significant because they are engaged in many mental and physical activities. This stage of life cycle is the prime time to build up body stores of nutrients in preparation for rapid growth of adolescence3.

Malnutrition manifests in different forms, such as under-nutrition, over-nutrition and micro-nutrients deficiency in children4. About 8, 26 and 16% of children worldwide suffer from wasting, stunting and underweight respectively. These figures are more in developing countries. According to UNICEF1 the prevalence of wasting is 10%, stunting 38% and underweight 23% in developing countries and 16.8, 27.6 and 61.2%, respectively in Nigeria. At the same time, overweight and obesity, which were previously considered problems afflicting mainly the affluent, are now markedly on the increase in low and middle income countries, particularly in urban areas5. In 2010, 43 million children (35 million in developing countries) were estimated to be overweight and obese, with 92 million at risk of overweight6. The prevalence rates of overweight and obesity in school-age children in Nigeria was 11.4 and 2.8%, respectively by Ene-Obong et al.7.

Malnutrition has continued to be a public health problem in developing countries where the poor socio-economic conditions work in synergy with malnutrition8. It is well documented that malnutrition negatively effects brain development causing delays in motor and cognitive development, such as: Attention deficit disorder, impaired school performance, decreased 1Q scores memory deficiency, reduced social skills, reduced language development, reduced problem solving abilities9. These might invariably lead to high withdrawal rate from school8,9. It is estimated that close to one billion children will be physically and mentally impaired globally by 2020 if interventions are not carried out10, global monitoring report11. According to World Food Programme12 66 million primary school-age children attend classes hungry across the developing countries and 23 million of these children live in Africa alone.

Government sponsored school programmes was launched by UNICEF13 with the aim of ensuring that every school child gets at least one adequate diet daily2,14. The programme is affected by the economic down turn especially in developing countries like Nigeria. In realization of the central role of nutrition in academic performance, the Federal Government of Nigeria in collaboration with New Partnership of African Development (NEPAD), World Food Program (WFP), United Nations International Children’s Fund (UNICEF) and International Development Partner (IDPS), piloted Home Grown School Feeding and Health Program (HGSFHP) in 12 states2,15 in 2005. The aim of GSFHP was to provide a nutritionally adequate meal during school hours while promoting food production by local farmers in the pilot states. Only one state (Osun state) is still implementing the programme in Nigeria15.

In many parts of Nigeria school children have a meal before they leave home for school and have no food until they get home late in the afternoon. Some children however, rush out to school with empty stomach. This problem is compounded with the increase of school hours from the usual 6-10 h. It is the sole responsibility of Nigerian parents to provide lunch for their children while in school. There is no guideline as to what to pack for the child. Mothers often face the challenge of deciding between what the child likes, what is available, affordable, easy to prepare and can remain in good condition after storage for hours in food flasks. Thus some mothers restore to packing no lunch or pack poor quality meal or just snacks. Despite the role of packed lunch in deterring poor nutritional status and cognitive development of school children, the question remain, are home-packed lunches nutritionally adequate and can provide 1/3 of the child’s RDI that is the main objective of the school lunch programme? This study assessed the nutrient content of home-packed school lunch and calculated the percentage of the RDI of the children met by the home-packed school lunch.

MATERIALS AND METHODS

Design, study location and subject: A cross sectional survey design was adopted. The study was carried out in Nsukka, the second largest city in Enugu State, South-East Nigeria. Nsukka lies on the North-West boarder of Enugu state and has a land mass of about 81 and 125 km2. The town houses the number one University in Nigeria and many secondary and primary schools. Two primary schools (Federal government university staff primary school and a private primary school) were purposively selected for the study. Both schools were in Nsukka urban. Multistage sampling technique was adopted in selection of the pupils. A total of 200 primary school children aged 5-8 years participated in the study. Informed consent of parents of the pupils and the school authorities were obtained after the purpose and full details of the study were explained to them.

Data collection: Data was collected using questionnaire validated by three experts from Department of Home Science, Nutrition and Dietetics, University of Nigeria, Nsukka. The questionnaire was taken home by the pupils for their mothers to complete and return. Packed lunch of each child was weighed for 3 days. The different lunches were weighed before the pupil started eating and the leftovers were weighed and subtracted from the initial quantities to determine the quantity consumed.

Data analysis: Statistical Package for Service Solution (SPSS) version 20 was used for data analysis. The mean nutrient contents of the home-packed school lunch were calculated using food composition table by Platt16. The values were compared with the recommended 1/3 of RDI for the age group required from school lunch.

RESULTS

The educational level and monthly income of parents of the pupils in primary schools in Nsukka showed that all the parents had formal education, 9.8% of them completed primary school education, while 71.3% were university graduates. About 52.4% of the parents had monthly income of 50,000 and above (Table 1).

Majority (90.2%) of the pupils ate breakfast before going to school, 78.3% were given home-packed meals, 15.4% had money to buy lunch from hawkers at school and 2.1% went to school with nothing (Table 2). Information on the amount of money given to pupil for school lunch indicates that 59.2% of the pupils had only home-packed lunch with no money. Among those given money, 36.4% had between 5- 30 and 3.5% of the pupils were given 30 and above (Table 3). The most commonly home-packed meals were jollof rice (40.9%), spaghetti/indomie noodles (30.1%) and bambara groundnut pudding (13.3%). The snacks included: Pastries (62.2%) and bread sandwich (4.5%).

Table 4 showed that 69.1% of the pupils did not take drinks (except water) to school, 8.1% took milk base drinks and 7.4% had fruit juice, while 5.9 and 9.6% took dried sorrel (Hibiscus sabdariffa) leaf drink and soft drinks, respectively.

Table 5 showed that the snacks bought from hawkers by the pupils included pastries (59.6%), roasted/boiled groundnut (12.3%), bambara groundnut pudding (10.5%), spiced fried cowpea cake (5.3%) and ice cream (5.3%). The nutrient contents of the commonly used home-packed meals/snacks/drinks were jollof rice 79.6 g carbohydrate, roasted/boiled groundnut 23.2 g protein and 0.79 mg vitamin B1, buns 7.0 mg niacin, among others. Some of the items were deficient in some of the nutrient examples buns vitamins A, C and iron, soft drinks protein, niacin, vitamins, zinc, biscuits and jollof rice vitamins A and C (Table 6).

The mean nutrient content of home-packed meals/snacks/drinks was 89.2 g carbohydrate, 14.3 g protein, 7.6 mg niacin, 0.41 mg vitamin B1, 30.6 μg vitamin A, 9.2 mg vitamin C. The zinc, potassium, iron and calcium contents were 5.12, 642.7, 3.46 and 36.72 mg (Table 7). The mean intakes of the pupils met 68% (1/2) for carbohydrate, 42% (1/3) for protein, 5% (1/20) for vitamin A, 35% (1/3) of iron and 4.5% (1/22) for calcium.

DISCUSSION

Most parents in the study were university graduates and had monthly income above 50,000. This could have influenced the choice of home-packed lunch for their children. This finding agreed with result of studies on assessment of nutritional status of primary school children17-19 the researchers found that socio-economic status of parents was a factor in the choice of lunch to pack for the children. Parents within the high income bracket sent their children to private schools where the content of home-packed lunch is taken as a reflection of socio-economic status of the parents.

Very high percentage (90.2%) of the pupils ate breakfast before going to school and 78.3% were also given home-packed lunch. Hoyland et al.20 and Lateef et al.21 recorded high percentage (86%) of breakfast consumption among school children. This was attributed to education and income of the parents. This practice is very healthy and might impact positively to the growth, development and academic performance of the pupils.

Table 6: Nutrient content of home-packed meals/snacks/drinks of pupils per hundred grams of edible portion

Table 7: Mean of nutrient content of home-packed lunch/snacks/drinks consumed and the percentage of RDI met by the pupils

Most pupils in this study were not given lunch money and among those who had money to buy lunch, majority of the pupils were given 5-10. This finding is in contrast with Ugochukwu et al.22 study which found that 80% of the pupils in private schools in Nnewi, Anambra state were given money to buy lunch from food vendors. This disparity in result could be attributed to location. Nnewi is a big commercial town East of Nigeria while the study area was a university town.

Verities of home-packed meals/snacks/drinks carried and eaten at school by the pupils includes: Popular meals Jollof rice, indomie noodles and bambara nut pudding. The snacks include pastries, bread sandwiches and drinks were milk base drinks, fruit juice, sorrel (Hibiscus sabdarffa) dried leaf drink and drinking water. The choice of these meals/snacks/drinks could be because of their nutrient contents so as to meet the RDI at school, availability, likeness by the pupils and convenience to carry to school.

Findings on types of meals/snacks/drinks bought by the pupils who were given money to school showed that various items purchased include: Pastries (59.6%), roasted/boiled groundnuts (12.3%), bambara nut pudding (10.5%), fried cowpea cake (5.3%) and ice-cream (5.3%). The choice may be influenced by the preference of the children and items that were available since the parents were not there to make choice for the pupils on things to buy (Table 5) this finding is in line with the findings of a similar study by Lateef et al.21, who indicated that the highest mean composite consumption per week by participants include: Snacks (pastries), ice-cream and different fruit juice.

Good number of pupils (89.2%) came with carbohydrate, meals/snacks good for energy supply. Few (14.3%) pupils came with protein based meals. Fruits and vegetables were left out except for very few (7.4%) pupils that came to school with fruit juice. Although, majority of the children (90%) came to school with home-packed meals/snacks/drinks, only few of them had adequate meals. The deficient nutrients in these meals/snacks/drinks could influence the optimal development of the pupils. Similar findings have been reported by both African and non-African studies by Briley et al.23 and Ogbimi and Ogunba24 reported that only 12% of preschool children had fruits in their lunch pack. This findings could explain that why researchers14,18,25 reported very high rate of malnutrition problems among primary school-age children.

Findings on the mean nutrient contents of the lunch/snacks/drinks consumed and the percentage of RDI met by the pupils indicates carbohydrate 68 g (1/2), protein 42 g (1/3), niacin 95 mg (1), vitamin B1 68 mg (1/2), vitamin A 5 μg (1/20), vitamin C 20 mg (1/5), zinc 51 mg (1/2), potassium 32 mg (1/3), iron 35 mg (1/3) and calcium 4.5 mg (1/22). The result of this study showed that carbohydrate, protein, niacin, vitamin B1, zinc and iron content of the home-packed lunch met 1/3 of the pupils RDI while calcium, vitamin A and vitamin C did not meet the required 1/3 of their RDI. This result is in line with the study by Meldrum26 in South Africa which revealed that the home-packed in township schools often met 50% of the pupils RDI. Previous studies by Senbanjo et al.17, Ogbimi and Ogunba24 and Babar et al.27 documented a strong link between poor socio-economic status and malnutrition which the findings of the present study showed where the nutrient contents of most of the home-packed meals/snacks/drinks met 1/3 of the pupils RDI. This was influenced by the parent’s high level of education and socio-economic status among others. The nutrients that could not meet up to 1/3 of the RDI could be as a result of poor food choices and combinations by the parents.

CONCLUSION

Majority of the pupils went to school with home-packed lunch which met the required 1/3 of the pupils RDI for protein, carbohydrate, iron, zinc, niacin and vitamin B1. The 1/3 of the RDI was not met for vitamins A, C and calcium. There is therefore great need for nutrition guidelines on food choices to guide parents and caregivers in providing adequate home-packed lunch for optimal growth, development and academic performance of school children.
