This study attempted to document the prevalence and factors associated with DBM at the national, regional, and state levels using a nationally representative dataset. DBM at the household level was reported as 3.4%, which is similar to previous studies conducted in India and other south Asian countries. A study conducted using NFHS 2015–16 data reported 4% households with overweight mothers and stunted child [32]. Further, a study conducted in 42 countries based on the demographic health survey (DHS) reported the prevalence of DBM as 1%, 1.2% and 1.5% in Bangladesh, India and Nepal utilizing data collected in 2000, 1998 and 2001 respectively [21]. Recently, a study reported the prevalence of DBM as 4.2%, 1.5%, 3.9% and 5.5% in Bangladesh, Nepal, Pakistan and Myanmar, respectively [29]. Another study reported that 11% and 4% of households in rural Indonesia (2000-03) and Bangladesh (2003-06), respectively, were double burdened [39]. These results indicate that the prevalence of DBM is increasing over time, highlighted the urgency for targeted interventions and attention of policy makers. This present study further showcased the prevalence of DBM at the state and regional level. The prevalence of DBM varied from 0.5% in Jharkhand to 10.4% in Kerala. A previous study conducted in Kerala reported a similar prevalence of DBM at the household level as 10.7% [31].
This study found that the prevalence of stunting among children less than 5 years of age was 33.9%. NFHS has reported 38% of stunted children across India ranging from 20% in Kerala to 48% in Bihar [40]. A study conducted in high burden pockets (districts) of India reported stunting as 37.9% in Madhya Pradesh to 70.7% in Jharkhand [41].This shows a huge variation in the prevalence of stunting in India at the state and district level. The prevalence of stunting was higher in rural areas (36.3%) than in urban areas (26.3%) and these findings corroborated with the findings from NFHS 2015–2016 [40]. This study also revealed that 15.3% of mothers were overweight or obese, whereas, NFHS 2015–2016 reported 21% of women as overweight or obese. This may be due the fact that the mothers of young children practice breastfeeding and therefore lose pregnancy weight [42].
This study further examined the maternal, child and household factors that are associated with DBM. Maternal characteristics, including mothers’ age, education, working status, caesarean delivery and mass media exposure were found to be associated with DBM. It was found that households with older mothers were at an increased risk of DBM as compared to those with younger mothers. This finding is in line with other studies [29, 39] and a possible explanation can be that with increasing age, chances of obesity increase due to a sedentary lifestyle and reduced metabolic rates. Another study also reported that maternal weight has been negatively associated with breastfeeding [42, 43]. Mothers’ education level was negatively associated with the prevalence of DBM at the household level. The finding corroborated with previous studies conducted in Pakistan [29] and Indonesia [39]. However, few studies documented that the risk of obesity among educated mothers was higher and can be attributed to a sedentary lifestyle [44]. Study households with mothers who had c-section deliveries were found to be at a higher risk of DBM. Studies suggest that obese mothers have a higher cesarean delivery rate[45]. In addition, children born via c-section delivery are less likely to have timely initiation of breastfeeding [46, 47].
Child characteristics, including age, sex, birth order and morbidity were examined and were found to be associated with DBM. Household with older children in age group of 24–59 months were at higher risk of DBM. These finding were similar to the studies conducted in Pakistan, Myanmar, Indonesia, and Bangladesh [29, 39]. One of the probable reasons can be that decreased breastfeeding and improper complementary feeding results in stunting among children age 24–59 [48]. Further, households with higher birth order of child were at increased risk of DBM. As the birth order increased so did the chances of a child being stunted, due to a preference for an older male child [49]. Further, with an increase in the number of live births, chances of maternal obesity increased by 7% per live birth [50].
The results of this study suggested that DBM was positively associated with higher wealth index of household and urban residence. Other studies in the South Asian region also reported the association of higher wealth index with DBM [19, 29, 39]and urban residence [29]. This is contradictory to the studies conducted in Latin American countries that report DBM association with lower wealth quintile and rural areas [51]. This contrast can be because of dietary habits. For instance, households in the higher wealth index had a higher consumption of energy dense food and aerated drinks. As the prevalence of obesity among women was high in urban areas [52], it contributed to the prevalence of DBM among urban households.
This study has several limitations. As this study used cross-sectional data, it limits the ability to draw causal inferences. Further, few important variables due to non-availability were not included in this study, such as physical activity and time use pattern of mothers to understand their lifestyles. In addition, genetic factors, which might have influenced both mother and child nutritional statuses, have not been assessed in this study.
DBM at the household level indicated the dual nutrition challenge facing India [37]. Addressing this complex issue is a crucial step towards achieving SDG-2. With unprecedented investment and focus on nutrition through the Poshan Abhiyaan programme, customized intervention, programme and policy can help overcome DBM and eventually smoothen the way to achieve SDG-2. The nutrition policies should focus not only on the diet of children but also on that of the mothers. Most of the child health programs focus on weight gain; therefore, stunting continues to remain a problem. Focus needs to be put on recommending a nutritious diet to overcome stunting along with other forms of malnutrition which co-exist in children. Mothers should also be recommended to have a nutritious diet and reduce energy-dense foods which lack nutrients. This will help reduce overweight and obesity and will also help in reducing other forms of malnutrition (micronutrient deficiency).
