Background: Ensuring the nutritional status of lactating women is crucial to prevent maternal morbidity and mortality in poor countries like Ethiopia. Hence, this study aimed to assess the prevalence of undernutrition and its associated factors among lactating women in Shebedino district, Sidama Regional State, Ethiopia. Methods: A community-based cross-sectional study was conducted among randomly selected 612 lactating women from February to March 2020. Data were collected by using an interviewer-administered, structured, and pretested questionnaire. Also, physical measurements (weight, height, and body mass index) were measured by using standardized and calibrated instruments. Data entered into Epi data version 3.1 and exported to SPSS version 23 for further analysis. Descriptive statistics, bivariable, and multivariable logistic regression analysis were done. A P-value of ≤.05 was used to consider the statistical significance. Result: The prevalence of undernutrition was 25.9% (95% CI: 22.5, 29.5). Having polygamous husband (AOR = 3.47, 95% CI: 1.13, 10.68), belonged to households with less than 5 members (AOR = 1.81, 95% CI: 1.16, 2.83), abortion history in the last 6 months (AOR = 3.09, 95% CI: 1.73, 5.51), poor household wealth status (AOR = 3.85, 95% CI: 1.89, 7.81), and medium wealth status (AOR = 2.07, 95% CI: 1.06, 4.03) were factors positively associated with undernutrition. Conclusion: Undernutrition among lactating women was high in the study area. Attention should be given to the economic status of the women, family planning services, abortion prevention, and habits of marrying more than 1 wife (polygamy).
This study was conducted in the Shebedino district which is located 27 km from Hawassa and 302 km from Addis Ababa, the capital of Sidama Regional state and Ethiopia, respectively. According to the Ethiopian Central Statistical Agency report, the total population of the district was 192,359. Among them, 51% are females. The district consists of 26 kebeles. It has a total of annually estimated 6656 (3.46%) lactating mothers. There are 6 health centers, 5 private clinics, and twenty-three health posts. 16 A community-based cross-sectional study design was conducted from February to March 2020. The source population for this study was all lactating women in the Shebedino district. All lactating mothers in randomly selected kebeles who fulfilled the eligibility criteria were the study population. Those mothers who had up to 24 months of the child, and lived in the study area at least for 6 months were included. However, those mothers who were seriously ill and unable to be interviewed during the data collection period were excluded. For the first objective, the sample size was calculated by using single population proportion formula based on the following assumptions: prevalence of undernutrition among lactating mothers (P = 40.6%) taken from the previous study, 23 10% of non-response rate, and design effect of 1.5, the final sample size was 612. From a total number of 26 kebeles (the smallest administrative unit in Ethiopia) found in the Shebedino district, 14 kebeles were selected by a lottery method. The lists of eligible households were obtained from pregnant women registration book at health posts in the selected kebeles. Then, a calculated sample size was proportionally allocated based on the number of eligible mothers obtained from each kebele. Community health agents were assigned with data collectors to access the eligible households. Finally, the study participants were selected by simple random sampling technique. Data were collected by using an interviewer-administered, pretested, and structured questionnaire. The questionnaire had different sections: socio-demographic characteristics of the respondents, items related to dietary practice assessment, and anthropometric measurements. Minimum dietary diversity score was obtained by collecting 24-hours dietary recalls as consumed/not consumed from different food groups. The score was calculated by using 10 food groups as the summation of consumed food. Anthropometric measurements (height, weight, and BMI) were measured by using standardized and calibrated instruments. Weight was measured to the nearest .1 kg on a battery-powered digital scale (Seca770, Hanover Germany), and height was measured to the nearest .1 cm using a wooden height-measuring board with a sliding head bar following standard anthropometric techniques. After checking for its completeness and consistencies, data were entered into Epi Data version 3.1 and exported to the Statistical Package for Social Science (SPSS) version 23 software for further analysis. Descriptive analysis was done for each predictor variable. A cross-tabulation was performed to see the distribution of predictors with the outcome variable. Bivariable logistic regression analysis was done for each independent variable with the outcome variable. Variables with a P-value of ≤.25 were entered into multivariable logistic regression analysis. The wealth index was constructed by using locally available tools related to ownership of selected household’s durable assets, domestic animals, and productive assets. Scores are derived by using principal component analysis. Wealth quintiles were compiled by assigning the household score to each usual household member, ranking by total score. The component with Eigenvalues greater than 1 was retained to construct the wealth index, and grouped into 3 socio-economic statuses as poor, medium, and rich. To check multicollinearity effect, variance inflation factor less than 10 and tolerance test greater than .1 was considered. Adjusted odds ratio (AOR) with a 95% confidence interval (CI) was calculated. A P-value ≤.05 was used to consider statistically significant variables. Finally, the results were described by texts and tables. All data collectors and supervisors were trained for 2 consecutive days on the general purpose of the survey and procedures. The tool was translated into local language (Sidaamu Afoo) and back to English by language experts to check its consistency. Instruments were calibrated before taking anthropometric measurements. A pretest was conducted on 5% of the sample outside of the study area. Collected data were checked for its completeness on daily manner, and all necessary modifications and measurements taken accordingly. In this study, underweight was the primary outcome variable of interest, defined as body mass index (BMI< 18.5 kg/m2). 2 In the final model (logistic regression analysis), we only considered underweight women and those with normal BMI and excluded those who were overweight and obese. The independent variables were socio-demographic factors (age, marital status, occupational status, level of education, household’s wealth index, and family size), obstetric and health care related factors (antenatal care, place of delivery, history of abortion, and mode of delivery), anthropometric measurements (weight, height, and BMI), and environmental factors (source of drinking water, availability of latrine, and waste disposal system). Undernutrition: According to this study, it is a nutritional status of lactating women (underweight) when BMI <18.5 kg/m2. Body mass index (BMI): Calculated as weight in kilograms divided by square of the height in meter.
