Maternal Nutrition Knowledge and Mothers' Ability to Utilize Mobile Phone Application for Health Information Sharing at Kenyatta National Hospital, Nairobi City, Kenya

The prevalence of maternal undernutrition has been reduced via numerous interventions, but it remains a global public health concern in underdeveloped countries. Pregnant women are increasingly using mobile phone applications to obtain, save, and share health information. This study evaluated maternal nutrition knowledge for the purposes of developing a mobile phone application-based health information sharing platform for pregnant women attending ante-natal care at Kenyatta National Hospital in Nairobi, Kenya. The study adopted cross-sectional descriptive and analytical study design. A food frequency and individual dietary diversity questionnaires were used to gather data on dietary consumption and diversity, while a semi-structured questionnaire was used to gather sociodemographic information from respondents who attended the antenatal clinic. Approximately 31.2% of respondents exhibited a high level of knowledge regarding mobile phone applications. Half of the participants (50.1%) demonstrated a moderate level of understanding, whereas 18.7% showed a low level of familiarity with mobile phone applications. About 19.9% met the minimum dietary diversity score, while 12.2% met the minimum meal frequency, and 26.7% met the minimum acceptable diet. Based on Mid-Upper Arm Circumference, 60% of the pregnant women had normal nutritional status, 36.9% moderate acute malnutrition while 3.1% had severe acute malnutrition. Significant association was observed between dietary diversity score and mobile phone application knowledge p ˂ 0.001. Additionally, nutritional status p ˂ 0.05 and level of education p ˂ 0.05, and mobile phone application knowledge of pregnant women showed significant associations. Despite the growing number of mHealth apps, the level of knowledge and usability of such apps by patients still remains relatively low. Nevertheless, the majority who used health apps found them to be beneficial, and agreed that it helped them to live a healthier lifestyle. Health apps have great potential in health promotion and therefore, to increase the use of these apps, it is necessary to first increase awareness and knowledge of these apps, both to the public and to healthcare professionals.
