ABSTRACT
OBJECTIVE(S): Although healthy dietary patterns are associated with decreased mortality in patients with chronic kidney disease (CKD), few patients receive dietitian counseling due to concerns such as dietitian availability, travel distance, and cost. Our objective was to determine the feasibility of dietary smartphone application-supported telecounseling to reduce sodium intake and improve dietary quality in patients with early CKD. METHODS: This was a pre-post, mixed methods feasibility study of 16 patients with Stage 1-3a CKD in central/northeast Pennsylvania. Patients recorded and shared dietary data via smartphone applications with registered dietitians, who used motivational interviewing to provide telephone counseling weekly for 8 weeks. Seven patients were assigned to a customized study-specific application and nine patients to a commercially available, free application (MyFitnessPal). Participant satisfaction was assessed via survey, and participants were invited to complete a semistructured interview. Outcomes assessed included sodium intake, Healthy Eating Index 2015 score, weight, and 24-hour blood pressure (BP). RESULTS: Mean age was 64.7 years, 31% were female, 100% were white, 13% had income <$25,000. Adherence was excellent with 14 (88%) entering dietary data at least 75% of total days. Patients reported high satisfaction with the intervention and dietitian telecounseling. Use of dietary apps was viewed positively for allowing tracking of sodium and energy intake although some participants experienced functionality issues with the customized application that were not generally experienced by those using the commercially available free application. Sodium intake (-604 mg/day, 95% confidence interval [CI]: -1,104 to -104), Healthy Eating Index 2015 score (3.97, 95% CI: 0.03-7.91), weight (-3.4, 95% CI: -6.6 to -0.1), daytime systolic BP (-5.8, 95% CI: -12.1 to 0.6), and daytime diastolic BP (-4.1, 95% CI: -7.9 to -0.2) improved after the intervention. CONCLUSIONS: An application-supported telecounseling program with a registered dietitian appears to be a feasible and well-accepted strategy to improve dietary quality and improve cardiovascular risk factors in patients with early kidney disease.

Trial Design: Excessive gestational weight gain (GWG) can increase pregnancy morbidity and is particularly problematic for women with pregestational obesity. A lifestyle modification intervention was introduced to gravida with obesity to decrease excessive GWG as compared to usual care (UC). Methods: A randomized controlled trial was conducted to improve healthy lifestyle behaviors to manage appropriate GWG. Consenting participants with prepregnancy obesity and singletons ≤17 weeks were randomized to (1) Usual Care (UC): usual written educational materials and counseling by obstetric provider or (2) Enhanced Care (EC): UC plus (a) personalized letter from physician detailing appropriate GWG; (b) access to individualized GWG chart; (c) ongoing counseling with registered dietitian/nutritionist (RDN). The primary outcome was proportion with GWG ≤9.1 kg, as this is upper limit recommended by Institute of Medicine (IOM). Total GWG and GWG as less than/within/greater than IOM recommendations (in aggregate and stratified by obesity class), and pregnancy/neonatal outcomes were evaluated as secondary outcomes. Results: Analyses included 105 participants in EC and 109 in UC arms. The groups had similar demographics: 46% with class I obesity, 26% class II, and 28% class III. There were no group differences for any GWG, pregnancy, or neonatal outcomes when analyzed in aggregate. As compared to those randomized to the EC arm, participants in UC arm with class I obesity gained 1.4 kg less and those with class II obesity were significantly more likely to gain within IOM guidelines (14.8% vs. 40.0%, adjusted p = 0.04). Participants with class III obesity randomized to EC arm were more likely to gain within IOM guidelines as compared to participants randomized to UC arm (29.0% vs. 6.7%, adjusted p = 0.02). Conclusion: There were no differences in GWG observed between groups when analyzing participants in aggregate. However, a physician's letter detailing appropriate GWG, patient portal access to a personalized GWG chart, and RDN consultation were helpful for encouraging GWG within IOM guidelines for women with prepregnancy class III obesity. Women with class I or II obesity had better GWG outcomes without these additional interventions.
