Results of the current study revealed that moderate stunting was significantly higher in El-Badrashine outpatient clinic patients (20%) presenting the rural area compared to 6.7% in urban Bolaque. Similar results were found in a study done by Mahfouz and collaborators, in which prevalence was 19.1% in rural upper Egypt [10]. Additionally, a study done in Suhag, which is a southern Egyptian governorate revealed more moderate stunting in rural areas compared to urban ones, but the numbers were higher than the current study (25.6% and 21.6% respectively) [11]. Moreover, a study done among children and adolescents living in the Middle East and North Africa region revealed that the prevalence of stunting was 34.1% in rural and 12.4% in urban areas [12]. In Tangail district in Bangladesh, Islam et al., (2014) reported moderate stunting among 144 under-five children to be 44.45% in rural and 2.78% in urban areas [13].
As regards mild (marginal) stunting, it was 33.3% in the studied patients from rural hospital, compared to 17.8% in the urban area. This disagrees with Islam and collaborators (2014) who reported marginal stunting to be 12.5% in rural compared to 16.6% in urban [13]. Nevertheless, the results of the current study agree with the latter authors in their report concerning severe stunting which is only present in their rural area patients (5.56%).
In the studied urban group, there were no underweight children, while 4.4% of children from the rural hospital were underweight. Similarly, a study done in Libya documented higher prevalence of underweight in rural areas (4.9%) than in urban areas (4.1%) [14]. Additionally, underweight was significantly more prevalent in the rural schools, in a study done in Morocco [15].
Mild or marginal underweight was detected among 15.6% of the urban area patients compared to rural ones who showed 22.2% marginal underweight. Similarly, in Tangail district of Bangladesh a higher percentage of children who had marginal underweight were in rural areas (38.8%) compared to urban (8.34%) [13].
Although Katsagoni and collaborators [16] documented that the Paediatric Yorkhill Malnutrition Score (PYMS) showed the best diagnostic accuracy compared to STAMP in pediatrics, the superiority of STAMP in detecting patients at risk of malnutrition compared to other screening stools as StrongKids was previously reported in literature [17-19].
STAMP was used as a malnutrition screening tool in the current study and its score results revealed that among the rural group 17.8% were at intermediate risk and 35.6% were at high risk of malnutrition. In the urban group 8.9% were at intermediate risk and 20% were at high risk. Higher percentages were reported in studies which screened hospitalized patients. For instance, in 2019, Moreno and collaboratorsfound a high risk of malnutrition in 48.3% of patients and a moderate risk in 48.2% and reported that the higher STAMP score was associated with longer length of hospital stay (P<0.01) and greater severity (P<0.01) [20].
Nutritional analysis of the study group intake showed higher intake in all macronutrients and micronutrients in patients from the urban hospital compared to rural one, but the differences were insignificant. This finding could contribute to the anthropometric measurements` differences between patients from studied urban and rural areas. From another prespective, in a study done by Abd El-Latife and collaboratorsin Sharkaia Egyptian governorate, the mean total intake of most nutritional components in the diet considerably exceeded the standards in both urban and rural preschool childrenwhich explained their finding of overweight among their series of rural and urban children(one in five and one in four respectively) [21].
Abdel-Rahman et al., reported that in Egypt, urban areas have captured the largest percentage of public health spending, whereas rural areas have invariably received less attention and are poorly funded which can explain the differences detected between the anthropometric measurements and nutritional data of the studied urban and rural areas. Moreover, rural areas are characterized by low levels of income, education, and economic development [22].Additionally, Sharaf and Rashad [23] suggested earlier that while child health has improved tremendously in Egypt, socioeconomic discrepancies remain considerable which can explain the more undernutrition burden in rural areas.
Concerning the effect of nutritional intervention program, there was significant increase in weight of children after 3 months in both rural and urban patients. Similar result was documented in Pradesh India, as 100 children aged from 13 to 36 months had significant weight gain after nutritional intervention program for 6 months [24], and in Kolkata India Debnath and Agrawal, documented weight gain after one-month nutritional intervention program among 104 three to six years old children [25].The latter authors also documented height gain in consistency with the current results.
The distinct though non-significant increase in BMI in the currently studied patients also agrees with the report of Debnath and Agrawal, [25].Additionally, there was improvement in STAMP score and an increase in almost all nutritional analysis parameters in the two studied groups after nutritional intervention program.
To explain the above findings, there was a significant increase in calories in patients from both urban and rural outpatient clinics after nutritional educational intervention which is consistent with Debnath and Agrawal who found that 32% of the children were taking less than optimal calorie intake daily, which decreased to 14% after nutrition education session leading to positive changes in children nutritional behavior [25]. Moreover, the increase in nutrients` intake in both studied groups upon nutritional rehabilitation, which reached statistical significance in many of them, is also countable because growth isn`t only about calories especially the height which can be influenced by more than one nutrient. In 2004 Ibrahim et al., concluded that several nutrient deficiencies occur simultaneously in stunted children and can be responsible for the condition among which zinc and magnesium were documented [26].
Based on the previous data, nutritional intervention program caused positive change in weight, height and nutritional behavior which led to decrease in childhood malnutrition. This agrees with Sawyer and collaborators, in Bayelsa State, in Nigeria, who documented that the nutrition intervention program delivered in a primary health care facility can positively change nutrition behavior and prevent childhood malnutrition [27].
Concerning STAMP score there was an inverse correlation between STAMP score and all initial study parameters as well as follow up data, which further proves its prognostic value (STAMP score decreased parallel to the increase in the nutritional intake and anthropometric measurements upon nutritional rehabilitation). This comes in agreement with McCarthy and collaborateurs [9]who reported that STAMP score is a reliable, specific, and sensitive nutritional screening tool in identifying nutrition risk.
In conclusion the studied Egyptian rural area showed more undernutrition burden compared to the urban location. Fortunately, screening of pediatric outpatient clinics allows early detection of malnutrition in children. This ensures prompt intervention tools including parent education and tailored nutritional plan which can lead to improvement of nutritional status disregards the location whether rural or urban.
Limitations
This study has its own limitations. The small sample size and the short nutritional rehabilitation period are among these limitations.
