The Effect of Web-Based and Face-to-face Training Given to Office Workers on Health Beliefs and Physical Activity Levels Regarding Obesity

Aim: This study was evaluated to compare the effects of web-based and face-to- face education given to office workers on health beliefs and physical activity levels towards obesity.

Material and Method: The research was conducted as a randomized controlled experimental study. The study population consisted of 768 office workers between February 2020 and April 2021, and the sample of the research consisted of 90 individuals selected from the population using the improbable random sampling method. "Descriptive Feature Form," "Obesity Health Belief Model Scale," "Physical Activity Questionnaire" were used to collect data. In the analysis of data; percentile distribution, chi-square, Fisher-Freeman-Halton Exact test, t-test in independent groups, Repeated Measures ANOVA Test, Friedman Test, One Way ANOVA test, Kruskall Wallis test, and post hoc analyzes (Bonferroni, Games Howell, Dunn) were used.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Physical activity level	Physical activity level Measures: The International Physical Activity Questionnaire(IPAQ) was used. When evaluating the activities of individuals, it is accepted that each activity is done for at least 10 minutes. "MET-min/week" score is obtained by multiplying "metabolic equivalent (MET) value", "day" and "minute" for each activity level. The MET energy values for IPAQ are as follows: "Walk = 3.3 MET" "Moderate-intensity physical activity = 4.0 METs" "Vigorous physical activity = 8.0 METs" Insufficient physical activity level 0 < Total MET-min/week < 600 Low level of physical activity sufficient 600 ≤ Total MET-min/week < 3000 Physical activity level sufficient 3000 ≥ MET-min/week	To the participants; initial assessment was made; Evaluation was made at the end of the 3rd month; Evaluation was done at the end of the 6th month. A total of 6 months of evaluation was made.
Health Belief Model Scale in Obesity	Health Belief Model Scale in Obesity Scale: Developed by Dedeli and Fadıloğlu in 2010, Health Belief Model Scale in Obesity Scale evaluates individuals' beliefs and attitudes towards weight loss. The cronbach alpha coefficient of the scale, which consists of a total of 32 items, is 0.80. The scores of the items belonging to each sub-scale of the scale are calculated by summing.Health Belief Model Scale in Obesity Scale sub dimensions: Importance of Health Perceived Sensitivity Perceived Severity Perceived Benefit Perceived Obstacle In the study, the increase in the score in the relevant sub-dimension indicates that the attitude in the relevant sub-dimension increased.	To the participants; initial assessment was made; Evaluation was made at the end of the 3rd month; Evaluation was done at the end of the 6th month. A total of 6 months of evaluation was made.
Body Mass Index	Body Mass Index Measures: Measurements were made with scales and meters. Weight and height will be combined to report BMI in kg/m^2.	To the participants; initial assessment was made; Evaluation was made at the end of the 3rd month; Evaluation was done at the end of the 6th month. A total of 6 months of evaluation was made.
Effect on sitting times	Effect on sitting times: How many hours do you sit in a day? created with the question.It was asked through the questionnaire. It shows that the situation worsens as the sitting time increases.	To the participants; initial assessment was made; Evaluation was made at the end of the 3rd month; Evaluation was done at the end of the 6th month. A total of 6 months of evaluation was made.
