Efficacy of Mobile Health Application in Promotion of Exclusive Breast Feeding and Young Child Feeding Practices in Pakistan

Every infant has the right to good nutrition. Early life nutrition is the key modifiable determinant of child growth, development, health, survival and chronic diseases of adult onset. The first year of infant's life provides a window of opportunity to improve health through adoption of recommended infant feeding practices. Breast milk is one of the first nutrition sources that a baby must be introduced to for optimum nutrition, health and growth. It is not only an important determinant of the nutritional status of the child but is also beneficial to strengthen the immune system of the baby and their sensory and cognitive development through creation of an intimate bond between the mother and her baby. Breast milk production and its consumption by the baby is also integral for the health of the mother, as it prevents the mother from ovarian and breast cancer and keeps her healthy for future pregnancies.

World Health Organization (WHO), therefore, recommends exclusive breastfeeding for up to 6 months and continued breastfeeding for at least 1 year for babies. Exclusive breast feeding is defined as 'infant receiving only breast milk without any food or drink, including water. Young Child Feeding Practices (YCFP) refers to the optimal feeding practices for a child aged between 6-12 months. This study aims to promote exclusive breastfeeding and young child feeding practices among women residing in the urban setup in the main city of Karachi, Pakistan, by the use of m-health intervention. WHO defines m-health as 'the use of mobile and wireless technologies to support the achievement of health objectives.

Pakistan is the sixth most populous country of the world. It is signatory to global agreement on reduction of under nutrition among children. Although, during the last decade (2011-18), proportion of underweight and stunted children has declined from 32% to 29%, and 44% to 40.2% respectively, proportion of wasting is showing an increasing trend from 15% to 17.7%. Further, the improvement achieved is not substantial. A quarter of newborns are born with low birth weight. Neonatal mortality rate (44.2/1000 live births (LBs) contributes 57% to the under-five mortality rate (74.9/1000 LBs) where breast feeding plays a crucial role for survival.

According to National Nutrition Survey 2018, only 48% of children under the age of 6 months are exclusively breast fed which is a suboptimal rise from 38% during 2012-13. The survey also highlighted that only 45.8% of infants were breastfed within 1 hour of birth. Likewise, only 35.9% of the infants between 6-8 months of age were weaned on age-appropriate complementary feeding, 14.2% receive minimum dietary diversity, 18.2% receive minimum meal frequency and 3.7% receive minimum acceptable diet. However, all these complementary feeding indicators are well below acceptable levels and are on decline compared to National Nutrition Survey 2011 except for dietary diversity. Below acceptable level of IYCF practices are found to be associated with maternal age, maternal illiteracy, unemployment, and poor household wealth status.

Province of Sindh has unsatisfactory infant and child nutritional indicators. Only 48% of mothers practice early initiation of breastfeeding within one hour of delivery while EBF is reported by 52.3% of the mothers. Similarly, only 43.5% of the children receive age-appropriate complementary feeding. Also, IYCF indicators of Sindh are poor compared to the other provinces of Pakistan. The proportions of children with minimum acceptable diet, minimum meal frequency and minimum dietary diversity are only 2.2%, 16.9% and 12.6% respectively and are lower than national estimates.

With the surge of technology use worldwide, the usage of mobile phone is also increasing in Pakistan. As per December 2019, there were 165 million cellular subscribers with 76 million 3G/4G users with smart phone penetration of 35.9% in Pakistan, though the usage is greater among males compared to females. Among women, 20% have access to a smartphone, 6% have a feature device while 23% have a basic mobile phone.

Mobile health (m-Health) has the potential to transform healthcare delivery by providing tailored and repeated information to individuals. Nowadays, a great bulk of the reproductive population has access to internet and socio media. Due to its increasing popularity, it bears the potential for delivery of intervention to a large number of people at a low cost.

However, such intervention has not been tested out in province of Sindh, in an urban setup where this technology use is increasing significantly over time. Hence, this study would be an important step in providing scientifically sound evidence to the limited pool of available literature on the effectiveness of m-Health interventions aimed at health care workers providing maternal and neonatal services in Low Middle Income Countries.
