The Effect of Phone Application Supported Nutrition Education on Weight Loss

Study Overview
=================
Brief Summary
-----------------
Internet-based applications are potential supporters for individuals in weight loss programs due to their accessibility and wide access. These applications are aimed at changing the lifestyle of individuals. This study is a randomized controlled study aiming to evaluate the effect of phone application supported nutrition education on weight loss according to standard education. It has been assumed that the telephone application would increase the adaptation and motivation of the people on diet. Anthropometric measurements and nutritional features of individuals, Weight Efficacy Lifestyle (WEL test), Quality of Life SF-36, Rosenberg Self-Esteem, Obese Individuals Specific Quality of Life, Healthy Life Style Behaviour Scale-II and Healthy Eating Index score changes questioned as intermediate variables. Between March and September 2018, 79 people aged between 18-64 years, whose BMI was 25 and more, who were admitted to the dietitian at Ege University Faculty of Medicine Hospital Endocrine and Metabolic Diseases Clinic and received routine nutrition education were included in the study. In the first interview, the data collection form of all individuals was filled out and anthropometric measurements of all individuals were made by the researcher. All individuals received a classic nutrition education by the clinical dietician and then written personal weight loss diets. Afterwards, only a control appointment for 3 months later was given to the control group. Phone application named Motive designed by the researcher uploaded to only case group's phone. With the telephone application text, visual and video notifications were sent to case group for 3 months.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Weight Loss | Body weight (kg) was measured at the beginning and end of the study by researcher | 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Body Mass Index (BMI) | BMI is calculated by dividing the body weight to the height 2 times. Weight was measured with TANITA BC 418 in the clinic. Height was measured with height meter in the clinic. BMI was calculated by researcher at the beginning and end of the study. | 3 months | 
| Body fat percentage (%) | Body fat percentage was measured with TANITA BC 418, which is available in the clinic by the researcher at the beginning and end of the study . | 3 months | 
| Waist circumference (cm) | It was measured from the midway of top of hip bone and the bottom of ribs by inelastic tape measure at the beginning and end of the study by researcher. | 3 months | 
| Neck circumference (cm) | It was measured from just under the larynx at the beginning and end of the study by researcher. | 3 months | 
| Weight Efficacy Lifestyle (WEL test) | The reliability and validity of the scale has been studied in Turkey. Index was questioned and calculated at the beginning and end of the study by researcher. The increase in the score shows a positive development. | 3 months | 
| Quality of Life SF-36 | The reliability and validity of the scale has been studied in Turkey. Index was questioned and calculated at the beginning and end of the study by researcher. The increase in the score shows a positive development. | 3 months | 
| Rosenberg Self-Esteem | The reliability and validity of the scale has been studied in Turkey. Index was questionedand calculated at the beginning and end of the study by researcher. Decreased Rosenberg self-esteem score indicates an increase in self-esteem. | 3 months |
