A parallel-group randomized controlled trial that will evaluate the efficacy of a mobile health (m-Health) program on influencing diet, supplement use and physical activity during pregnancy. Pregnant women will be randomly assigned to the intervention and the non-intervention arm. The intervention arm will receive free of cost m-Health application that will screen on the diet, supplement use and physical activity at enrollment and at 4 follow-ups, each 6 weeks apart. Based on the information provided by women, they will receive personalised recommendations based on an algorithm developed using the World Health Organization's guidelines on nutrition during pregnancy and American College of Obstetricians and Gynaecologists guidelines for physical activity during pregnancy. The non-intervention arm will receive standard face-face counselling. The changes in diet and supplement use of both groups will be assessed using the Dietary Risk Score. Also, biochemical assessment of micronutrients will be carried out on a subset. the change in physical activity will be assessed by the mean duration of reported activity. The secondary outcomes include the evaluation of compliance and usability of the m-Health application. Also, the effect of the m-Health application on maternal, newborn and infant outcomes will be assessed.
A parallel-group randomized controlled trial will be implemented with pregnant women at the antenatal clinics of the Aga Khan University Hospital (AKUH) Karachi. Pregnant women in their first trimester, registered or planning to register at AKUH with access to personal smartphones with internet connection will be considered eligible for the study. For pregnant women in the intervention arm, mobile health application will be provided on their smartphones that will screen their socio-demographic characteristics, diet and supplement use and physical activity habits. Based on the information provided by women, personalized recommendations and a dietary risk score will be generated upon completion of the questionnaire. A similar process will be repeated on 4 follow-ups, each 6 weeks apart after enrollment in the study. Also, push notifications consisting of tips and recommendations will be sent to women a maximum of 3 times a week on dietary, supplement use and physical activity. The women in the non-intervention arm will be provided with standard face-face counselling at similar time points as of intervention group, using the bilingual educational leaflet of the Aga Khan University Hospital "Diet during Pregnancy" and the American College of Obstetricians and Gynaecologists guidelines for physical activity during pregnancy. The primary outcome of the study is improvement in the dietary and supplement use that will be assessed through Dietary Risk Score. A selective subset of participants from both the group will undergo free of cost biochemical assessment micronutrients (serum calcium, vitamin D, iron and folate). The secondary outcomes include assessing the compliance and usability of m-Health application among the pregnant women enrolled in the intervention arm. Other secondary outcomes include evaluating the effect of m-Health coaching on maternal, newborn and infant outcomes among pregnant women in the intervention arm compared to the pregnant women in the non-intervention arm

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Mobile Health Coaching Program during pregnancy | Experimental | Eligible pregnant women would be randomized to intervention or the non-intervention arm after consenting to participate. Participants in the intervention arm will receive free subscription of m-Health program for six months of coaching. The program will provide individualized coaching on diet, supplement use and physical activity. Participants would undergo dietary screening at five points i.e. at baseline and at 6, 12, 18 and 24 weeks follow-up to monitor the improvement (if any) in diet, supplement use and physical activity. Women will receive advice in the form of recommendations after completing the questionnaire. Also, push messages containing tips and recommendations for diet, supplement use and physical activity would be delivered a maximum of three times a week. Furthermore, a subset of participants would undergo objective dietary assessment through biochemical testing of serum folate, serum ferritin, and serum calcium and serum vitamin D at baseline and at end line. |
|
| Standard Counseling | No Intervention | For the non-intervention arm, dietary counseling will be provided face to face by the trained research assistant at the baseline and scheduled follow-ups using the AKUH educational leaflet "Diet during Pregnancy" and American College of obstetricians and gynaecologists guidelines for physical activity. Alike intervention group, the non-intervention group will complete an interviewer based paperless screening questionnaire at five points i.e. at baseline and at 6, 12, 18 and 24 weeks follow up. Furthermore, a subset of participants would undergo objective dietary assessment through biochemical testing of serum folate, serum ferritin, and serum calcium and serum vitamin D at baseline and at end line. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Mobile Health Intervention | Behavioral | A mobile based application will be developed that will function on android as well as the iPhone operating system. The application will be provided to eligible pregnant women randomized to the intervention group. The dietary, supplement use and physical activity coaching will be provided over the period of 6 months through the application. |
| Measure | Description | Time Frame |
|---|---|---|
| Dietary Risk Score (DRS) | Dietary Risk Scores (DRSs) will be calculated based on the consumption of food items from six main food groups and will range from 0-18. Based on the portions and quality of diet, the score for each group will be 0, 1.5 or 3. The total score will be the sum of individual group scores. Higher the aggregate score, poorer the dietary quantity and quality and vice versa. Hence, a score of 18 will indicate a highly inadequate dietary intake; a score of 9 denotes nearly adequate and a score of 0, an adequate diet. | 6 months, from enrollment till last follow-up |
| Supplement use Score | Supplement use will be assessed by recording the frequency of consumption of folic acid, iron, calcium and vitamin D in the questionnaire. The frequency will be categorized as daily (7 days a week), often (4-6 days a week) and sometimes (1-3 days a week). Also, a total score ranging from 0-12 will be assigned where each supplement use will be scored 0 for daily, 1.5 for less than daily and 3 for no consumption. The total score will be the sum of each supplement score and will be monitored at each follow-up. | 6 months, from enrollment till last follow-up |
| Biochemical Assessment of serum folate at baseline | A subset of pregnant women from each group will be selected systematically for the biochemical testing of serum folate at the baseline screening | 1 week of enrollment |
| Biochemical Assessment of serum ferritin at baseline | A subset of pregnant women from each group will be selected systematically for the biochemical testing of serum ferritin at the baseline screening | 1 week of enrollment |
| Biochemical Assessment of serum calcium at baseline | A subset of pregnant women from each group will be selected systematically for the biochemical testing of serum calcium at the baseline screening |
| Measure | Description | Time Frame |
|---|---|---|
| Compliance with the intervention | Percentage of participants who would complete the six months' program. | 24 week of enrollment |
| Usability of mobile health program | Usability of the web-based program will be assessed at the end of the study using a digital evaluation form containing 26 questions with a five response categories Likert-type scale as strongly agree, agree, neutral, disagree and strongly disagree OR always, often, sometimes, rarely and never. it will be assessed under three categories: (i) design and interface, (ii) content and coaching and (iii) perception and personal benefit. |
