Introduction
Community daycare centres (Anganwadi centres) in India are started as part of the Integrated Child Development Service program to combat child hunger and malnutrition. A total of 1.396 million Anganwadi Centres (AWCs) are registered in the country [
1]. Out of which 0.136 million are in urban areas whereas the rest are in rural areas of the country. Under-weight based on weight-for-age, is recommended as the indicator to assess changes in the magnitude of malnutrition over time [
2]. Evidence has shown that the mortality risk of children who are even mildly underweight is increased, and severely underweight children are at even higher risk [
3]. Thus, monitoring weight-for-age can help assess the contribution of public health policies or interventions to mortality reduction.
In India, 26 million children are born every year. Children (0-6 years) comprise 13% of the country’s total population [
4]. Studying malnutrition in under-five children is important from a public health perspective. Intending to improve the nutritional and health status of children in the age group of 0-6 years, the government of India in 1975 launched ‘The Integrated Child Development Services (ICDS)’; AWCs is part of it [
5]. AWCs provide nutrition and nutrition education, non-formal preschool education, and health education. Referral services, health check-up and immunization is also provided at AWCs which is part of public health system.
Earlier studies have found that there are various risk factors associated with malnutrition among under-five children. Gender differences, families with low per capita income, urban-rural lifestyle, lower food consumption in girls compared to boys, poor feeding practices, and lack of knowledge about growth monitoring in children are some of the determinants [
6].
Place of residence, household wealth, birth weight, age of a child, awareness regarding diarrheal diseases and acute respiratory tract infection control, maternal education, number of under five years children, and source of drinking water were strong predictors of child nutritional status in developing countries [
7]. Maternal factors like age, weight, and anaemia also affect a child’s nutritional status [
8]. There is a positive link between the nutritional status of children and the stages of development in the states they live [
9].
Recent studies have revealed internet access plays an important role in improving the energy intake of low-income groups which should be considered in terms of the UN’s Sustainable Development Goals (SDGs) of ending malnutrition [
10]. A few more studies prove the internet’s role in tackling malnutrition [
11,
12,
13].
The COVID-19 pandemic has unearthed our reliance on broadband internet, not as a luxury but as an essential utility such as water and electricity [
14]. Broadband internet access is a super determinant of health because many other social determinants like education, health care, food, income hinge on it [
15].
Infrastructure development has a positive role in public health. There is no study available to show whether there is any effect of community infrastructure like public daycare centers or internet access to women on reducing under-five malnutrition, especially in the Indian context. This study is designed to understand, if any positive relation persists between community infrastructure (daycare centers and internet access to women) in the reduction of child malnutrition. The results will be used to fill the knowledge gap and to frame strategic policies to obtain better results.
2. Methods
2.1. Study Population
Our sample consisted of 724,115 women in the age group of 15-49 years. The majority of India’s population growth comes from rural and underprivileged areas, while the rise in income comes from the urban privileged population. So, studying both populations were considered to help better understand the issue. Population is divided into four sub-samples for study-Urban women, rural women, urban children, and rural children. For a detailed understanding of the geographical prevalence of underweight children in the country, the study population was divided into regions.
1)The northern region- has six states- Himachal Pradesh, Punjab, Uttarakhand, Haryana, Delhi, and Uttar Pradesh; 2) The southern region contains five states- Andhra Pradesh, Karnataka, Kerala, Tamil Nadu, and Telangana; 3)Eastern region- is consisting of the states of Bihar, Jharkhand, Odisha and West Bengal, 4)Western region states are Rajasthan, Maharashtra Gujarat and Goa; 5) Central region-It consists of two states- Madhya Pradesh and Chhattisgarh 6)North-East region includes-eight States viz. Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura. Union territories (Andaman and Nicobar Islands, Chandigarh, Dadra and Nagar Haveli, Daman and Diu, Lakshadweep, Puducherry, Jammu & Kashmir, Ladakh) are grouped as per their geographical locations.
2.2. Database Used for Study
The data related to the percentage of underweight children and the percentage of women getting Internet Access was collected from the Ministry of Health and Family Welfare (MoHFW), Government of India. Data related to the number of Anganwadi centers per state has been collected from the Ministry of Women and Child Development. The NFHS-5 data provides information for 707 districts, 28 states, and 8 Union territories (UTs). The survey work for the NFHS-5 was planned in two phases. The first phase was carried out for 17 states and 5 Union territories from 17 June 2019 to 30 January 2020 and the second phase has been completed in 11 States and 3 UTs from 2 January 2020 to 30 April 2021.
Weight was measured with an electronic SECA 874 flat scale designed for mobile use. Height was measured with a Seca 213. stadiometer. Underweight (assessed via weight-for-age) is a composite index of height-for-age and weight-for-height. It takes into account both acute and chronic undernutrition. Children whose weight-for-age Z-score is below minus two standard deviations (-2 SD) from the median of the reference population are classified as underweight. Children whose weight-for-age Z-score is below minus three standard deviations (-3 SD) from the median are considered severely underweight (based on WHO standards).
2.3. Ethics Approval
Our study is based on the publicly available dataset of the NFHS-5 surveys with no identifiable information on the participants and can be freely accessed from the Ministry of Health and Family Welfare website, India. As per the data, the ethical approval for the NFHS-5 surveys is obtained from the ethics review board of the International Institute for Population Sciences, Mumbai, India. These surveys are reviewed and approved by the ICF Institutional Review Board, USA. Informed written consent for participation in this survey is obtained from the respondents during the survey. Each individual’s approval is sought before the patient interview, as per the consistent methodology followed in these national surveys.
2.4. Study Variables
The primary outcome variable or dependent variable in this study is the percentage of underweight children. The independent variable or explanatory variable is the number of AWCs per state (%) and the percentage of women getting Internet Access. The information on the women getting Internet access and AWCs was obtained by asking ‘yes’ or ‘no’ questions orally. Children whose weight-for-age Z-score is below minus two standard deviations (-2 SD) from the median of the reference population are classified as underweight. Children whose weight-for-age Z-score is below minus three standard deviations (-3 SD) from the median are considered severely underweight (based on WHO standards).
2.5. Statistical Analysis
Descriptive statistical analysis of the data has been done. Mean, median and range was calculated. Pearson correlation coefficient analysis, simple linear regression and multiple linear regression was carried out for independent variables, operational AWCs (%) and women with Internet access (%), and dependent variable underweight children per state (%). Social Science Statistics (
www.socscistatistics.com) tools are used for above analysis.
Result
National-level data on the percentage of women with Internet Access shows, urban women (51.8%), rural women (24.6%), and total (33.3%). Whereas the percentage of underweight children in urban India (27.3%), rural (33.8%), and total 32.1% (
Table 1) (
Figure 1). The regression analysis results in this study show a linear correlation between the variables of internet access to women and children under five years who are underweight (weight-for-age) in India. Here Ꞵ coefficient is -0.36 (p < 0.001) means that when you increase internet access to women by 1, the value of Y which is the percentage of underweight children decreases by 0.3552.
The simple linear regression analysis of the independent variable AWCs (%) in state and dependent variable, percentage of underweight children per state shows Ꞵ= 1.46, p < 0.001. R-squared (R2) equals 0.3366. This means that 33.7% of the variability of Y is explained by X.
Multiple linear regression was done for independent variables, operational AWCs (%) and women with Internet access (%), and dependent variable underweight children per state (%). The model developed is Underweight children (%) = 37.1607 + 0.5659. operational AWCs (%) – 0.2907. women with Internet Access (%). It shows Ꞵ0= 37.1607, Ꞵ1= 0.5659, and Ꞵ2= -0.2907 as well as R squared value as 0.5709. This shows independent variables have a significant influence on the number of underweight children in the state.
Results of the Pearson correlation indicated that there is a significant large positive relationship between operational AWCs (%) and the percentage of underweight children in the state, (r(34) = .58, p < .001). Results of the Pearson correlation indicated that there is a significant large negative relationship between Internet access to women (%) and the percentage of underweight children in the state, (r(34) = .733/-0.733, p < .001).
The above statistical analysis shows that access to the Internet for women has a significant role in reducing the percentage of underweight children when compared to AWCs.
In every state of northern India, the percentage of urban women with internet access is higher than in rural areas (
Table 2). The mean of women with internet access is 63.58 in urban areas as compared to 45.35 in rural. The average of total women with internet access is 51.92 for the country’s northern region. Punjab (17.9%), Uttarakhand (21.0%), and Delhi (22.2%) were the northern states where a greater number of urban children were underweight than their rural counterparts. Jammu and Kashmir (21.0%), Himachal Pradesh (25.5%), and Ladakh (20.4%) have shown an increase in the percentage of underweight children when compared to NFHS4 data. In contrast, the rest of the states of northern India have shown a reduction in the percentage of underweight children.
In the northern region of India, Uttar Pradesh has shown the highest number of AWCs (189024) followed by Jammu and Kashmir (28119), Punjab (27314), Haryana (25963), Uttarakhand (20088), Himachal Pradesh (18925), and Delhi (10899). Despite having the maximum number of AWCs in Uttar Pradesh; the highest number (32.1%) of underweight children are observed here. Union territories like Ladakh (1144), and Chandigarh (450) have a smaller number of AWCs. When comparing the results of Union territories of Jammu & Kashmir with Chandigarh the percentage of underweight children is similar. The number of AWCs in Jammu & Kashmir is very high if compared with Chandigarh. The only variable of internet access to women varies here. The UT of Chandigarh has a higher percentage of women with internet access as compared to J & K.
As far as internet access to women is concerned in all the states of southern India, urban women are more in number than rural women. In southern states of India, the Union Territories of Lakshadweep (28.5%) and Puducherry (15.9%) have shown more underweight children in urban areas as compared to rural areas. The states of Telangana (31.8%), Kerala (19.7%), and the Union Territories of Lakshadweep (25.8%) and Andaman & Nicobar (23.7%) have shown an increase in the percentage of total number of underweight children compared to NFHS4 data. In this region, the UT of Puducherry showed the lowest number of underweight children (15.3%) with only 855 AWCS. This is the area where the highest number of women with internet access (61.9%) is seen in the region (
Table 3).
In the Eastern region of India, in every state, more urban women have access to the Internet as compared to the rural ones. Jharkhand (31.4%) has the highest percentage of women with internet access in the region compared to the other regional states. It is followed by West Bengal (25.5%), Odisha (24.9%), and Bihar (20.6%). In the Eastern region of India, West Bengal (32.2%) has shown an increased percentage of underweight children compared to NHFS-4 data.
In the eastern region of India, the highest number of underweight children is in Bihar (41.0%) whereas the lowest number of underweight children is in Odisha (29.7%). If the number of AWCs is compared, in Bihar 114989 AWCs are there whereas in Odisha 74157 AWCs are there. The better nutrition results in Odisha might be due to the better internet access for women (
Table 4).
In the Western region of India, urban as well as rural women of Goa are more in number for access to the internet. Goa is followed by Maharashtra (38.0%), Rajasthan (36.9%), UT of Dadra and Nagar Haveli (36.7%), and Gujrat (30.8%) for total women who got internet access. In the Western region of India, except Rajasthan, the rest of the states have shown a slight increase in the percentage of underweight children when compared to NFHS-4 data. The lowest number (24.0%) of underweight children are found in Goa with only 1262 AWCs. The state shows the highest number of women (73.7%) with Internet access (
Table 5).
In Chhattisgarh and Madhya Pradesh of Central India, double the number of urban women have access to the internet as compared to rural women. In the Central region of India, the declining percentage of underweight children is observed when compared to NHFS-4 data. States of Chhattisgarh and Madhya Pradesh of Central region have similar numbers of women with internet access. At the same time, more or less similar numbers of underweight children. Despite the considerable difference in the number of AWCs between the states, the comparable results might be due to access to the Internet for women (
Table 6).
In North-Eastern India, urban Sikkim (90%), followed by Mizoram (83.8%) and Arunachal Pradesh (70.0%) have the highest number of women with internet access, not only in the North-East region but also in the other parts of the country. In rural parts of the states, this number is lower than in urban parts of the region. The state of Tripura has the lowest number of women with internet access in urban (36.6%) as well as in rural (17.7%) parts. In the North-Eastern region of India, Assam (32.8 %), Mizoram (12.7%) and Nagaland (26.9%) have shown an increase in the underweight children population when compared with NHFS-4 data.
Mizoram has shown the lowest number of underweight children (12.7%) in the North-east region whereas the highest number of underweight children (32.8%) are seen in Assam. Mizoram has 2244 AWCs whereas Assam has 61738 AWCs. When the data for Internet access for women is compared, Mizoram has (67.6%) more women with Internet access than the women in Assam (28.2%) (
Table 7).
When the mean (average) was compared for the geographical regions of the country the Eastern region showed the highest number of AWCs (87504.75) whereas the Northeast had shown lowest number of AWCs (12807.88). But when the mean of the percentage of underweight children for various geographical regions is analyzed the highest number of underweight children (35.58%) is seen in the eastern region whereas the lowest number of underweight children is seen in the North-east region (22.11%) of the country (
Figure 2).
When the mean was calculated for Internet access and the percentage of malnourished children for each geographical region of India, North India has the highest number of women with Internet access (51.92%). North is followed by the northeast (47.21%) region, west (43.22%), south (42.95%), central (26.8%), and east (25.6%) (
Figure 3).
The eastern region has shown (35.58%) the highest number of underweight children. This region is followed by west (33.22%), central (32.15%), south (25.1%), north (22.31%), and northeast (22.11%). Compared to NFHS4, the mean of all these geographical regions for underweight children shows a reduction except for the northeast region.
When the range was calculated for various geographical regions, the highest value of range was observed for Internet access for Northeast India (53.8). That means the difference in Internet access to different states here is more. Some states have women with more internet access and some states have less. Northeast is followed by North (44.6), west (42.9), south (40.9), East (10.8), and Central (0.2) regions.
When the range was compared for the percentage of underweight children in various geographical regions, the Northeast showed the maximum value (20.1). It is followed by south (17.6), west (15.7), north (15.2), east (11.3) and central (1.7). When the range was compared for operational AWCs for all geographical regions, the North showed the highest (188574) range followed by west (110024), east (84011), south (65819), north-east (60430), and central (45249).
Discussion
Earlier studies have proved the role of community-based childcare centers in improving child nutrition and development [
16]. Our study clearly shows when compared with Internet access to women, AWCs have a limited role in the nutrition of the child. Internet access to the mothers can be one of the possible determinants of improving child’s nutrition.
About half of all fatalities in children under five are attributable to under-nutrition [
17]. Asia is home to over 70% of malnourished children, with India, Pakistan, and Bangladesh having the highest prevalence in this region [
18]. In the digital age, the penetration of the internet and social media has become the determinants of lifestyle changes and consequent health outcomes [
19].
Our study results are similar to the earlier studies where the urban or rural area was the determinant of child malnutrition [
20,
21]. A study in northern Ethiopia where children born to rural mothers were more likely to be severely underweight than children born to urban mothers. The reason behind the rural-urban gap might be in urban areas women get more access to information regarding child nutrition, health services, and feeding practices [
22].
A similar urban-rural divide was noticed in the Bangladesh population where access to primary education, household socioeconomic status, adequate maternal healthcare utilization, improvement of transportation, and awareness about nutrition in urban areas compared to rural ones are the determinants behind this divide [
23]. Urban children from families with higher average monthly income do not show the problem of under-nutrition may be due to higher levels of income increasing their ability to provide more than enough nutrition for their growing children [
24].
Similar to our study geographical variation and urban-rural variation was noticed in earlier studies [
25]. Here children of higher birth orders (4 or more) living in rural areas of Central, eastern, and north-eastern regions of the country are benefitting from Anganwadi centres. Anganwadi centres provide mid-day meals to children throughout the country especially in rural areas via the government-run Integrated Child Development Scheme (ICDS). Urban children generally don’t have access to these Anganwadi centres. Locally available food variety and social customs related to dietary habits are also reasons behind the geographic variations in the adequate diet of children [
26].
The contributing factors for undernutrition may differ from one region to another [
27]. In our study, the variation was noticed at the state level as well as regional levels. Our results are similar to the results of the study carried out in Ethiopia for understanding the cluster variation of underweight and detecting spatial heterogeneity at the sub-national level over time [
28]. This will be useful for identifying gaps in child nutrition programs at the state level and coming up with targeted nutritional interventions for the population at risk.
A prevalence study carried out in the Population of Nepal shows the similar effect of the socioeconomic divide on the outcomes of child nutrition. This study suggests context-specific health information education and communication (IEC)/behaviour change communication (BCC) materials such as radio jingles, posters, pamphlets, and other pictorials can be designed in the local languages and delivered through multiple channels so that messages can be reached out to disadvantaged communities [
29]. This applies to the Indian population also where by spreading health information in regional languages via the internet, the government can cost-effectively reach the maximum population.
Studies have proved Internet access significantly facilitates healthcare access and mitigates the negative impact of income inequality on healthcare access [
30,
31].
In our study, some states have shown a higher number of under-weight children in their urban areas compared to rural ones. Our results match the earlier studies where the prevalence of underweight was more seen in an urban slum than in a rural area [
32,
33]. It was observed in these studies that the low income of the family had resulted in underweight children from an urban slum.
A study carried out in Bangladesh has also showed more underweight children in urban slums than in rural ones. The study says, that for people living in slums, poverty is perceived with income and consumption patterns. In the majority of cases, the poor are involved in stumpy-earning jobs and often have inadequate income which subsequently results in spending the majority of their earnings on food, mainly staples like rice, cereals, lentils, potatoes, and vegetables, and usually evade costly items like meat and poultry, milk, and fruits. There are schools of thought, that indicate that chronic malnutrition and undernutrition among children are often the result of deprivation of such necessary food items over a long period [
34].
In recent years the Internet has become a popular source of health information [
35,
36]. There are research studies show a relationship between internet technology and dietary health. These effects are mixed. A significant positive association was seen between internet use and fast-food consumption in rural Chinese children [
37]. In contrast, a study in Iran shows nutrition knowledge from the Internet can improve dietary quality [
38].
A study carried out on the Indian population shows eHealth movement is underway within healthcare systems in developing countries but the adoption of eHealth resources remains low [
39]. This study shows demographics, health beliefs, and technology enablers are the significant factors for the use of eHealth. These factors influence the prevalence of Internet Health Information Seeking (IHIS), the diversity of IHIS, and discussing Internet Health Information with doctors. Understanding the factors affecting the health digitization process can help better promote eHealth adoption in developing countries like India.
A study carried out in Africa for the implementation of universal health coverage suggests Innovative strategies such as digital health. Certainly, the successful deployment of it on a wider scale faces several challenges for geographically diverse countries like India. Digital health has several benefits namely improving access to healthcare services, especially for those living in remote areas, improvements in safety and quality of healthcare services and products, improved knowledge and access of health workers and communities to health information; cost savings and efficiencies in health services delivery; and improvements in access to the social, economic and environmental determinants of health, all of which could contribute to the attainment of universal health coverage. Similar to Africa, India too faces the challenges in deployment of digital health like weak health systems, lack of awareness and knowledge about digital health, and poor infrastructure such as unstable power supply, and poor internet connectivity [
40].
India has 40 cities with over a million population, 396 cities with between 1,00,000 and 1 million, and 2500 cities with between 10,000 and 1,00,000 [
41]. The internet and electricity should be provided in these areas on a priority basis. Studies have shown, that the diffusion of the Internet has dramatically reduced informational frictions and given people unprecedented sources of health information [
42,
43,
44]. The use of the internet by women is directly related to the education of women and the internet access to them.
Nutrition education has a significant impact on increasing maternal knowledge and children’s nutritional status. Earlier studies also suggest that nutrition health education methods and media can be booklets, guidebooks, leaflets, and internet technology applications [
45].
