Isa Mohammadi Zeidi and Amir Pakpour Hajiagha

Obesity and overweight is a major health problem in many developing countries. The prevalence of obesity is higher in women and hypertension, Hyperlipidemia, diabetes, cancer, gallstones and hormonal disorders are more common in obese people. Preventive interventions such as motivational interviewing (MI) that focusing on lifestyle modification and maintain proper weight is more cost effective than surgery or medications. The present research aimed to determine the impact of MI on dietary habits and BMI among obese or overweight women. In a quasi-experimental study, 120 obese and overweight women using multistage sampling were selected to participate randomly in control and experimental groups. The intervention consisted of five sessions of MI in small group which was presented to experimental group. Data were collected before and three months after MI. Dietary intake was evaluated using 24 hour dietary frequency for 2 days and food frequency questionnaire (FFQ) for 3 months. Also, Stadiometer and weight gauge were used to measure height and weight. Finally, data was entered into SPSS 17.0. Descriptive statistics (mean and standard deviation) were used for continuous variables and number and percentage were applied for categorical variables. Also, Chi-square tests, paired and independent t-test was used for data analysis. The results indicate a significant increase in the consumption of bread and Cereals, milk and dairy products, fruits and vegetables and beans in the experimental group after MI interviewing (P < 0.001). Also, the consumption of meat and its substitutes,  oils and fats and sugar significantly reduced in the experimental group after MI (P < 0.001). Additionally,  results indicated a significant reduction in body weight (P < 0.001) and BMI (P < 0.05) in the experimental group after MI. The results suggest that MI is added to healthy lifestyle training programs in order to avoid the risks of overweight and obesity.
