Severe acute malnutrition; Hypoglycemia under five children; Ethiopia

Introduction

At least one-third of all child fatalities worldwide are caused by malnutrition, which is a serious issue for global health. A state of abnormally low blood glucose levels is known as hypoglycemia. The definition of hypoglycemia varies within the scientific literature and across clinical practice but is defined by the WHO as RBS

The hippocampus is particularly sensitive to hypoglycemia and can lead to deficits in cognitive development, particularly with regard to working memory. Severe acute malnutrition (SAM) is thought to predispose children to develop either hypoglycemia. Low glycogen stores and wasting with reduced lean mass and adipose tissue reserves have been linked to hypoglycemia in SAM. In addition, hepatic glucose production has been found to be lower, especially in children with edematous SAM(11). he WHO guidelines on the inpatient treatment of SAM at nutritional rehabilitation units recommend small, 2–3 hourly feeds in the early stages of treatment to prevent episodes of hypoglycemia [1,2].

It is believed that children with severe acute malnutrition (SAM) are more likely to experience either hypo or hyperglycemia. Low glycogen stores and wasting with reduced lean mass and adipose tissue reserves have been linked to hypoglycemia in SAM. Hormonal changes with impaired insulin responses as well as impaired glucose clearance could potentially increase the risk of hyperglycemia in SAM. When compared to developed countries, hypoglycemia with SAM is a common health problem in developing countries. This is evident when visiting almost any hospital in a developing country, where severely malnourished children and hypoglycemia are likely to account for a significant proportion of pediatric mortality. Hypoglycemia with severe acute malnutrition is a common and serious condition that increases the mortality rate of children. Hypoglycemia in children with severe acute malnutrition can be easily treated and managed at a low cost, but there is a lack of awareness and materials in developing countries to assess hypoglycemia early in children with severe acute malnutrition. This study is intended to provide information and data on the prevalence of hypoglycemia among malnourished children admitted to health facilities. Such data is important for reassessing, evaluating, and reforming the policy. Reviewing previous studies on hypoglycemia in the malnourished yielded no clear and adequate data. The gap was addressed in this study. The goal of this study is to reduce morbidity and mortality associated with hypoglycemia caused by malnutrition and its risk factors [3].

Methods and Materials

Study design, area and period

A retrospective institutional-based cross-sectional study was conducted at public hospitals in the East Gojjam Zone from August 1 to August 30, 2022. This study was conducted at East Gojjam Zone public hospitals, Amara Region, Ethiopia. Debre Markos Town is the capital of the East Gojjam Zone, which is 254 kilometers away from Bahirdar, the capital of the Amhara National Regional State, and 304 kilometers away from Addis Ababa, the capital of Ethiopia. The study areas are Debre Markos Comprehensive Specialized Hospital, Lumamie Primary Hospital, and Bichena Primary Hospital. Debre Markos Comprehensive Specialized Hospital has a catchment area and five primary hospitals. The hospital provides care for around 5,000,000 of the population of Debre Markos town and its neighboring catchment area, and most of its patients come from the lower socioeconomic area; it admits 14 SAM patients per month. Lumamie primary hospital provides care for 154,612 of the population of Lumama town and has 3 SAM patients per month admitted to it. Bichena primary hospital provides care for around 522,000 of the population of Bichena town, including its catchment area, and had 5 SAM patients per month flow through it [4].

Eligible criteria and inclusion criteria

Under-five children admitted with SAM at the public hospital in East Gojjam Zone from 2018 to 2021 were included in this study. Children with incomplete data were excluded (i.e., outcome variable, age, sex, residence, routine medication, unknown admission and discharge date).

Sample size determination and sampling technique

Sample size determination

The sample size was determined using the single population proportion formula. The following assumptions were made: that the marginal error (d) on either side of the true proportion was 5%, that a 95% confidence level was used, P= In an Ethiopian study of children with SAM, hypoglycemia was found to be the most common comorbidity and complication on admission, affecting 8.8% of children admitted to the stabilize center at Gedo zone. In order to maximize precision in our study, we used the lowest possible margin of error (d) of 3%, or 0.03 [5].

Sampling procedure and technique

Under-five children with SAM admitted to public hospitals in East Gojjam Zone from 2018 to 2021 were obtained. Each year, the number of admitted children was counted. The medical record was extracted within the defined period, and a unique number was assigned. The samples were proportionally allocated for each year. Each year, the final sample size was determined using a simple random sampling method [6].

Variable of the study

Dependent variable: Hypoglycemia with SAM Independent variable: socio-demographic and admission status (age, sex, residence, history of TB contact and presence of edema, appetite test, admission criteria). Comorbidity (diarrhea, cough/pneumonia, malaria, sepsis, superficial infection (skin or ear infection), severe anemia, fever, HIV/AIDS, vomiting, hypothermia, hyperthermia)

Operational definition

Hypoglycemia: occurs when the random blood sugar level falls below 54 mg/dL.

SAM: the presence of nutritional edema (bilateral pitting edema) or severe wasting (MUAC < 11.5 cm or a WFH < -3 z-score [WHO standards]) in children > 6 months old.

New admission: patients who are directly admitted to inpatient care to start the nutritional treatment.

Defaulted: SAM cases that are signed (by parents on behalf of their child) against treatment to leave treatment before cure or lost for 2 consecutive days with unknown status

Relapse: If that patient has ever been severely malnourished before and cured.

Marasmic-kwash: SAM cases with both edema and severe wasting [7].

Data collection tool and procedure

Data collection has been done using a structured data extraction format accomplished by reviewing children’s medical record charts and the HMIS log book. After carefully observing the medical records of the children an appropriate data extraction checklist was made. The questionnaire was developed in English and used to collect data after being pre-tested before the study period. A modification of the questionnaire was made based on the pre-test. Socio-demographic characteristics, medical comorbidities, and treatment are given and follow-up characteristics of the study subject in the course of treatment of hypoglycemia with SAM. The data collection tools were adapted from several different related studies of hypoglycemia with SAM. Four BSc nurses working in the malnutrition center were collected for the data by reviewing children’s medical record charts and the HMIS log book [8].

Data quality control

The data was extracted by staff nurses working in malnutrition centers who were familiar with the malnutrition follow-up form. Two days of introductions about the objectives, significance, and variables of the research, and how to extract the data by using the data extraction tools were given to four data collectors and two supervisors. To assess the consistency of the data extraction tools, a pretest was performed on approximately 5% of the charts at Dejen Primary Hospital. The data collection process was closely monitored by the supervisors and the principal investigator for its completeness and consistency [9].

Data analysis technique

Data was checked for its completeness and consistency, then entered into SPSS and analyzed. SPSS 25 version statistical software was used for cleaning, coding, and analysis. Descriptive statistics were computed for categorical variables. The primary outcome variable was categorized as "0" for without hypoglycemia individuals and "1" for hypoglycemia with SAM individuals. The goodness-of-fit of the model was checked by the Hosmer–Lemeshow test. After checking the multi-collinearity and interaction terms, each independent variable with a p-value 10].

Result

Socio-demographic characteristics

From 2018 to 2021, 378 under-five patients with severe acute malnutrition were admitted to East Gojjam zone Public Hospitals, with a 100% response rate. Out of 378 children, 240 were male (63.5%). In total, 308 (81.5%) of the respondents were aged 6-59 months; additionally, the majority of the children came from 250 rural (66.1%) homes, and half of the Marasmus respondents, 192 (50.8%), were 131 (34.7%). The 378 SAM children had a mean weight of 6.21 kg (SD = 4.61) and a mean height or length of 72.28 cm (SD = 13.8) at admission. (Table 1)

Medical comorbidities

There was no found hypoglycemia in 261 (69%) of the 378 SAM patients who presented, and 50 (13.2%) had found hypoglycemia with SAM. During admission, all but one of the respondents (346 out of 91.5) had comorbidity. (Table 2)

Treatment given and follow up characteristics

East Gojjam Zone Public Hospitals used the national guideline for SAM Ethiopia inpatient treatment protocol for treatment given and follow-up characteristics of under-five children with SAM. Due to that, those under-five children admitted to the SAM room took different types of routine medication at admission, such as ampicillin and gentamicin (41.8%), amoxicillin (22.7%), and Albendazole or Mebendazole (8.7%). (Table 3)

Factors associated with hypoglycemic among severe acute malnutrition

In the bivariate analysis, sex, age, residence, admission status, MUAC at admission, Appetite test at admission, shock, failure to treatment, TB, child who had given ReSoMal, type of IV medication and immunization status were associated with significant variables. In contrast, age, shock and children fully immunized were significantly associated with hypoglycemia among SAM in multivariate logistic regression analysis (P-value less than 0.05).

Age was significantly associated with hypoglycemia with SAM; children admitted between the ages of 0-6 months were 5.9 times more likely than those admitted between the ages of 6 and 59 months to develop hypoglycemia [AOR: 5.92 (2.41–14.52, p=0.000)]. Children who had shock were 4.4 times more likely than those who did not have shock to develop hypoglycemia among SAM [AOR: 4.35 (1.12– 16.91, p = 0.034)]. Children who had fully immunized were 2.6 times more likely than those who did not have yet immunized to develop hypoglycemia among SAM (AOR: 2.61 (1.01- 6.77, p=0.048) (Table 4).

Discussion

In this study, a total of 378 sampled retrospective data records were reviewed, and the prevalence of hypoglycemia was 13.2% (95% CI: 0.1- 0.17). The study is lower than the study conducted in India (21.9%).

Again, there was retrospective bias, and only 27% of patients had a blood glucose recorded in this system within 4 hours of admission WHO standards. In our study, 50 of 378 (13.2%) SAM patients were admitted to three hospitals, including the East Gojjam Zone Public Hospital, for a retrospective study. A study conducted in Kenya examined the utility of the WHO protocol for a retrospective study of children with SAM and discovered a prevalence of hypoglycemia of 13.6%, This might be due to differences, in hospital facilities; skills of professionals, adherence to management protocol, the severity of cases, and comorbidity attributed to these variations.

The magnitude of hypoglycemia with SAM in our study was 13.2%, which is higher than the previous study in Ethiopia, Children with SAM who had hypoglycemia made up 8.8% of those admitted to the Gedo Zone. The prevalence of hypoglycemia in SAM patients with comorbid pneumonia was 35 (9.3%) in this study, 14.3% in the previous study in Ethiopia and in Malawi 7 out of 176 (4%) SAM patients were recorded to have hypoglycemia in the first 24 hours of admission based on an electronic medical records database. The other study showed a retrospective analysis of case notes, relying on hypoglycemia being recognized and tested for; the prevalence of hypoglycemia was therefore likely underestimated based on observational data ranging from 1.3% to31%.

Children admitted between the ages of 0 and 6 months were 3 times more likely than those admitted between the ages of 6 and 59 months to develop hypoglycemia. This might be because the ages of 0 and 6 months of life are extremely important for the growth and development of children. And it is a time when most malnutrition cases occur because it is a transition time from exclusive breastfeeding to complementary feeding.

Children who had shock were 5 times more likely than those who did not have shock to develop hypoglycemia among SAM. This finding was similar with previously conducted studies in Ethiopia Gedeon Zone and Mozambique of which shock was identified as the main determinant of death. This is because children with SAM are highly at risk of shock secondary to severe infections and diarrheal diseases, which can cause either hypovolemic or septic shocks. Besides, severe sepsis and diarrheal diseases in malnourished children might be associated with low cardiac reserves, leading to shock, which leads to death. Another possible explanation for the high fatality rate among children who got IV fluids is that the IV fluids prescribed to the children throughout the research period may not have adequately corrected their shock. This would be consistent with a study that compared the use of half-strength Darrow's solution with the use of the isotonic solution in children with SAM and reported inadequate shock correction in all study arms, leading to a decision to end the trial early.

Children who had been fully immunized were 3 times more likely than those who did not have yet been immunized to develop hypoglycemia among SAM. Malnourished children consequently stand to gain a great deal from vaccination, but given that it is the most prevalent immunodeficiency in the world, they may not be able to respond to immunizations as well as they could. Given that recurrent infections contribute to the pathophysiology of the illness, immunization may be essential for preventing malnutrition. The 10 greatest evidence-based nutrition-specific interventions are thought to minimize stunting by just 20%, highlighting the necessity for additional strategies, including as infection control, to prevent growth failure in infancy. However, it is difficult to pinpoint the specific contribution of vaccination. Multi-sectorial interventions have proven the most successful in lowering the prevalence of stunting. Immunizations against one disease are unlikely to have a large impact on growth; rather, it is becoming more and more obvious that a combination of therapies is required to combat malnutrition.

This study revealed that children with SAM are at risk of hypoor hyperglycemia, and hypoglycemia relates to clinical outcomes like mortality. Give emphasis to screening hypoglycemia in SAM patients with regard to treating and preventing hypoglycemia. As this is a hospital-based secondary data analysis, further prospective studies are needed to identify the prevalence of hypoglycemia and risk factors for severe acute malnutrition in children.
