Effect of Educational Short Message Service (SMS) on Excessive Gestational Weight Gain (GWG)

Abstract Objectives The objective of this trial was to investigate the effect of educational short message service (SMS), or text messages, on gestational weight gain (GWG) in a low-income population. It was expected that the intervention group, which received text messages on nutrition and physical activity during pregnancy, would experience less GWG when compared to the control group. Methods Participants (n = 83) were recruited at WIC clinics on the island of O‘ahu, Hawai‘i at 15–20 weeks gestational age. Eligibility criteria were: body mass index (BMI) of 25–45 kg/m2 in the first trimester, 18 years of age or older at the time of recruitment, and possession of a cellular phone with the ability to receive text messages. After recruitment, participants were randomized into intervention (n = 42) and control (n = 41) groups. The intervention group received SMS on nutrition and physical activity during pregnancy per the Institute of Medicine and American College of Obstetricians and Gynecologists guidelines, respectively. The control group received SMS about general health topics during pregnancy. Both groups received one text message per week for eighteen weeks. GWG was defined as the difference between the last weight taken before delivery and participants’ self-reported weight before pregnancy. GWG in intervention and control groups was compared using a linear regression model. Results Women were age 27.7 ± 5.3y on average, 65.5% were Native Hawaiian, Pacific Islander or American Indian, 54.8% had some college or more and 37.8% were employed. The average weight before pregnancy was higher in the intervention group (80.6 + 17.7 kg) than that in the control group (76.2 + 15.9 kg), but this difference was not significant (P = 0.24). GWG was lower in the control group (14.1 + 11.4 kg) compared to the intervention group (15.5 + 11.6 kg), but this result was not significant (P = 0.58). Conclusions There was no significant difference in gestational weight gain between the intervention and control groups. Trials that begin earlier in pregnancy or before pregnancy with longer interventions and more frequent messages are needed.

Objectives: The objective of this trial was to investigate the effect of educational short message service (SMS), or text messages, on excessive gestational weight gain (GWG) in a low-income, predominantly overweight/obese population. Methods: Participants (n = 83) were mostly overweight/obese women recruited at Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) clinics on the island of O’ahu, Hawai’i at 15–20 weeks gestational age. The intervention group received SMS on nutrition and physical activity during pregnancy designed to help them meet Institute of Medicine (IOM) guidelines for GWG and American College of Obstetricians and Gynecologists guidelines for exercise, respectively. The control group received SMS about general health topics during pregnancy, excluding nutrition and physical activity. Both groups received one text message per week for eighteen weeks. GWG was defined as the difference between the last self-reported weight taken before delivery and participants’ self-reported weight before pregnancy. Differences between study groups were examined using t-tests and Chi-square tests. Linear regression models were used to examine association of GWG with study group and other factors. Results: GWG was similar (p = 0.58) in the control group (14.1 ± 11.4 kg) and the intervention group (15.5 ± 11.6 kg). The percentage of participants exceeding IOM guidelines for GWG was similar (p = 0.51) in the control group (50.0%, n = 17) and the intervention group (60.5%, n = 23). Conclusions: GWG was not significantly different between intervention and control groups. Trials that begin earlier in pregnancy or before pregnancy with longer intervention durations and varying message frequency as well as personalized or interactive messages may be needed to produce significant improvements.

Abstract Objectives Higher energy intake has been associated with increased gestational weight gain (GWG). However, the effects that individual macronutrients have on GWG remain unclear. We examined the putative mediating effect of macronutrient composition on GWG after an intervention aimed to track prenatal energy needs. Methods In this controlled trial, pregnant women aged >18 yr old (X = 29.8 ± 4.9 yr) with a gestational age (GA) <17 wk were randomized to Breezing™ (N = 16) or control (N = 12) groups for 13 wk. The Breezing™ group used a real-time metabolism tracker to obtain their resting energy expenditure. Anthropometrics and diet data were collected every 2 weeks. Overall rate of GWG was calculated as total weight gain divided by total study weeks. Early (GA wk 14–21), late (GA wk 21–28), and overall (GA wk 14–28) changes in macronutrients and GWG were calculated. Simple mediation models were constructed using SPSS PROCESS macro Model 4 using a bootstrap estimation approach with 5000 samples. Results There was no difference in total (8.13 vs. 7.17 kg, P = 0.37) or rate (0.58 vs. 0.53 kg/wk, P = 0.57) of GWG among Breezing or control groups. Breezing women gained significantly more [F(1,24) = 5.29, P = 0.03] and had a higher rate of GWG [F(1,24) = 4.48, P = 0.05] in the latter half of the 2nd trimester. Women gained more than the recommended GWG based on study start BMI. Early, late, and overall total energy (kcal/d), fat (g/d), and carbohydrate (g/d) intakes were not different between groups. Late changes in protein significantly differed [–15.62 vs. 24.86 g/d, t(26) = –2.92, P < 0.01] among Breezing and control groups, which explained 25% of the variance. A difference in overall change in protein intake between the Breezing and control groups (–0.94 vs. 21.77 g/d) approached significance [t(26) = 1.77, P = 0.08]. There was no mediation effect of early, late, or overall changes in macronutrients on GWG. Overall, a trend emerged, that for each one gram increase in protein, there was a decrease in total GWG of 0.02 kg [β = –0.02, t(26) = –1.75, P = 0.09] in the late half of the 2nd trimester. Conclusions Macronutrient composition did not mediate the intervention effect probably due to the study being underpowered to detect mediation. However, use of the Breezing device significantly predicted late changes in protein intake, suggesting that variability in maternal protein intake may influence GWG.

Abstract Background There is sparse in the literature on resting energy expenditure guided intervention to manage gestational weight gain in obese and overweight women.Methods We conducted a prospective cohort study in Beijing, China between May 1, 2017 and April 30, 2018. Obese/overweight women who visited the Department of Obstetrics and Gynecology at LuHe hospital of Capital Medical University, a tertiary care facility in Beijing, China, for their routine prenatal care at 10-13 weeks of gestation during the study period were recruited into the study after written consent was obtained. Women whose pre-pregnant body mass index was < 25Kg/m2 or who took steroid medication or those diagnosed with thyroid disease or affected by pre-pregnant diabetes mellitus or for other reasons could not participate in the study assessments were excluded. Participants who were recruited between May 1, 2017 and December 30, 2017 were the designated control group with diet recommendation based on pre-pregnancy body mass index and ideal weight, without resting energy expenditure monitoring. Those who were recruited between November 1, 2017 and April 30, 2018 were the intervention group, with resting energy expenditure guided diet recommendation to manage gestational weight gain. Gestational weight gain and perinatal outcomes between the two study groups were then compared.Results A total of 53 eligible women (32 in intervention group and 21 in control group) were recruited and included in the final analysis. There was no difference in baseline demographic and clinical characteristics between the two groups. Gestational weight gain in the intervention group (13.45±4.16 Kg) was lower than in the control group (18.20±4.84 Kg). Rate of macrosomia in the intervention group (3.12%) was also lower than in the control group (19.05%). There was no fetal growth restriction observed in either group.

Abstract Background Maternal nutritional status is an important determinant of intrauterine growth and neonatal size. No published surveys exist on maternal Mediterranean diet intakes and newborn adiposity. The aim of the study was to evaluate the impact of the individual maternal Mediterranean diet on the in-utero body fat formation and cord leptin level in newborns. Pregnant women with a pre-pregnancy body mass index (BMI) between 30 and 35 kg/m2 (n = 118) were assisted for individual dietary counseling based on the Mediterranean diet healthy eating. According to diet adherence, participants (paired mother and newborn) were divided into an intervention group (n = 57) and a control group (n = 61). We examined the association between diet modification and gestational weight gain, maternal, and cord leptin level together with newborn anthropometry (weight and fat mass %). Results Gestational weight gain, newborn birth weight, fat mass %, and cord leptin level lower in the intervention (12.22 ± 1.8 kg, 3.57 ± 0.35 kg, 9.27 ± 2.16 %, 11.78 ± 3.63 ng/ml, p = 000, respectively) than in control group (18.03 ± 3.25 kg, 4.02 ± 0.32 kg, 11.85 ± 2.30 %, 35.37 ± 11.14 ng/ml, respectively. Umbilical cord leptin levels strongly correlated with neonatal fat mass percent in both groups. However, maternal serum leptin did not correlate with the newborn parameters in the intervention group. Conclusion Maternal energy intake from healthy fat and diet intervention is probably associated with decreased fat mass and leptin levels in neonates.

Background and Purpose: Studies have shown that maternal obesity and excessive gestational weight gain (GWG) lead to adverse health outcomes for the mother and her offspring. Yet, knowledge of the best way to intervene is still lacking. The objective of this study was to develop, pilot and evaluate a sustainable intervention to prevent excessive GWG among participants of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in southern California. Methods: We conducted a prospective cohort study where the intervention group received an individual education program that included a GWG tracker. The historical control group was a group of women from the same WIC site who gave birth before the start of the intervention, therefore did not receive the intervention. Chi-square tests and t-tests were used to compare characteristics of the control and intervention groups and the proportions of women exceeding the Institute of Medicine (IOM) recommendations for GWG. Results: The impact of the intervention was strongest for overweight women. 62.5% of the control group gained more than the recommended amount compared to 48.6% in the intervention group. Conclusion: A simple weight tracking intervention could be a cost-neutral way to help WIC participants avoid excessive GWG.

BACKGROUND Traditional dietary recommendations for achieving optimal gestational weight gain are ineffective for pregnant women due to the lack of real-time communication and tedious consultation processes. OBJECTIVE In this pilot study, we aimed to determine the feasibility of a novel food-coaching smartphone app for controlling gestational weight gain and macronutrient intake among overweight and obese pregnant women. METHODS We designed a randomized controlled trial and recruited 30 overweight and obese pregnant women (1:1 ratio) during 18-20 weeks of gestation and followed them up after 4 and 8 weeks, respectively. Both groups received standard pregnancy dietary orientation at recruitment, while the intervention group received 8 weeks of real-time food coaching via a smartphone app. This food-coaching smartphone app (Glycoleap, Holmusk, Singapore) aimed to improve care and outcomes for people with diabetes. Pregnant women using this app were able to upload food images (eg, a picture of a meal, a drink, or a dessert) and received real-time and detailed food-coaching comments and guidance provided by professional dietitians during the day (8 AM to 8 PM). We recorded detailed characteristics during recruitment and examined anthropometry at all visits. We compared the mean differences of the 8-week gestational weight gain and macronutrient intake between the two groups. RESULTS Upon study completion, three subjects dropped out from the intervention, and one gave birth prematurely in the control group. The acceptance rate of the smartphone app was 90%. More participants achieved optimal gestational weight gain per week in the intervention group (8/12, 67%) than in the control group (5/14, 36%). After the 8-week intervention, women in the intervention group appeared to have lower gestational weight gain (mean difference=–0.08 kg; 95% CI –1.80 to 1.63) and cholesterol intake (mean difference=–31.73 mg; 95% CI –102.91 to 39.45) than those in the control group. CONCLUSIONS Our findings showed that this food-coaching smartphone app is feasible and favorable for weight gain control and cholesterol intake control among overweight and obese pregnant women. Although our results were not significant (perhaps, attributed to the small sample size), it provided proof of concept for the feasibility of applying such technology in future randomized controlled trials with a larger sample size, an earlier intervention onset, and a longer follow-up for overweight and obese pregnant women.

Abstract Background Excessive gestational weight gain (eGWG) is one of the major metabolic risks for fetal macrosomia, maternal overweight, gestational diabetes mellitus (GDM), and gestational hypertension during pregnancy, which also increase the risk of postpartum weight retention. Gestational weight gain (GWG) management is rising to be attractive during prenatal care, however, there is still lack of effective tools to assist health care providers (HCPs) to efficiently and continuously implement intervention and monitor from the early phase of pregnancy. The current study tested a prototype eHealth solution aiming to assist clinicians to prevent eGWG and associated gestational metabolic complications. Methods A randomized controlled study was conducted in a private hospital in Beijing, China, with control group (N = 181) and intervention group (N = 181) recruited in rolling fashion. The control group received standard prenatal care, while the intervention group was additionally provided with the integrated prenatal care eHealth solution, Pregnancy Butler, which includes mobile application-enabled on-line service and off-line consultation session. The prevalence of eGWG, associated metabolic health parameters, and final pregnancy outcome were evaluated. Results Although mostly with normal pre-pregnancy BMI, the incidence for eGWG was high among the study subjects, at 35%. Engagement with the eHealth platform of the intervention group was stable after initial phase, but less than desired. Pregnancy Butler intervention showed significant benefit (p-value = 0.0496) in preventing eGWG among obese and overweight subjects. And highly engaged active users in the intervention group had more favorable GWG classification (p-value = 0.022). The time-course data collected indicated that the metabolic risks were largely set early in the first trimester already. Conclusions Our preliminary results indicated that the effectiveness of the eHealth intervention considerably depend on each participant’s engagement level and baseline risk factors. In order to achieve more consistent and impactful outcome improvement, focusing on those with pre-existing metabolic risks, increasing engagement and adherence level, and emphasizing intervention from the first trimester could be promising directions. Trial registration: This study was retrospectively registered as “Pregnancy Butler for gestational weight gain management” (ChiCTR1800014647) under the China Clinical Trial Registry in 2018-Jan-26. http://www.chictr.org.cn/showprojen.aspx?proj=24171

Gestational weight gain (GWG) in the intervention group (13.45±4.16 Kg) was lower than in the control group (18.20±4.84 Kg). Rate of excess GWG in the intervention group (37.59%) was also lower than in the control group (66.67%). The REE in women of the intervention group with excess GWG increased faster than women with appropriate GWG during pregnancy, especially from 1st trimester to 2nd trimester. Rate of macrosomia in the intervention group (3.12%) was lower than in the control group (19.05%). There was no fetal growth restriction observed in either group. Conclusion: Resting energy expenditure guided nutrition intervention during pregnancy may lower GWG and lower incidence of macrosomia, with no apparent impact on fetal growth restriction. Future studies with larger sample size and randomized controlled trial design are needed to confirm findings from this small-scale study.

Iron supplementation is a government program to overcome anemia among expectant mothers, and some of the expectant mothers still do not obediently consume iron tablets. Therefore, to increase the obedience of the expectant mothers on consuming the iron tablets, SMS reminder is the appropriate method needed. This research aims to identify the effectiveness of SMS reminder to the obedience of iron tablets consumption among expectant mothers at UPT Puskesmas Cibuntu , Bandung. The research employed quasi-experimental design with posttest-only control group design using purposive sampling technique. The research was held on April–May 2014 at UPT Puskesmas Cibuntu, Bandung. Forty expectant mothers consuming iron tablets disobediently divided into 20 intervention groups and 20 control groups were taken as the samples. Questionnaire in form of self report was used to obtain data. In addition, descriptive analysis and chi square test were applied to analyze the data. The result of the research showed that 17 persons (85%) of intervention groups were mostly obedient, and 16 persons (80%) of control groups were mostly disobedient. From the analysis using chi square, it was found the difference of the obedience of iron tablets consumption after SMS reminder (p=0.00) had been delivered with significant level <0.05. Based on the result of this research, SMS reminder had an effective impact toward the obedience of iron tablets consumption among the expectant mothers. The result will be a good consideration for Puskesmas to cooperate with provider or proposed some funds to Dinas Kesehatan to activate SMS reminder.Key words:Expectant mothers, obedience, SMS reminder, iron tablets
