Brief Summary

Sexuality is integral to personality, influencing feelings, thoughts, actions, and physical and mental health. Female sexual dysfunction is a fairly common condition that covers four main areas: hypoactive sexual desire disorder, arousal disorder, orgasmic disorder, and sexual pain disorder. Although incidence and prevalence rates vary, it has been reported that women range between 30% and 50%. Male sexual dysfunction is not a single disease. Male sexual arousal refers to the entire process of sexual activity for men, including penile erection, penile penetration, ejaculation, and any obstruction in a single connection. It is a significant psychological distress for affected men, their sexual partners, and their health-related quality of life. Sexual dysfunctions are common among men of all ages and ethnic and cultural backgrounds. It is reported in the literature that 52% of men between the ages of 40-70 experience various degrees of sexual dysfunction. Cardiovascular disease, smoking, obesity, sedentary lifestyle, diabetes, hypertension, hyperlipidemia, and metabolic syndrome are risk factors for sexual dysfunction. Although the positive effects of adopting healthy lifestyle changes and dietary habits in reducing the risks of these diseases have been proven, few studies have evaluated the impact of these treatment approaches on sexual dysfunction. Studies evaluating the relationship between diet and erectile dysfunction have focused more on men with diabetes. Some small studies have also shown that lifestyle modification and weight loss interventions improve erectile dysfunction in men with significant cardiovascular risks. The same is valid for female sexual dysfunction. The Western diet and its components are indirectly associated with sexual morbidity. The Western diet has processed foods, refined carbohydrates, and high sodium and monounsaturated fat content, which have been widely linked to the development of MetS, obesity, and diabetes. These comorbidities are also risk factors for female sexual dysfunction as well. This study aims to evaluate the relationship between the eating habits of obese and non-obese men and women and their sexual functions.

Outcome Measures

Primary Outcomes (6)

• Sexual function in obese women [ Time Frame: through study completion, an average of 6 months]

  A domain score of zero indicates that the subject reported having no sexual activity during the past month Desire: Score Range 1-5; Min-Max score 1.2-6.0 Arousal: Score Range 0-5; Min-Max score 0-6.0 Lubrication: Score Range 0-5; Min-Max score 0-6.0 Orgasm: Score Range 0 (or 1)-5; Min-Max score 0-6.0 Satisfaction: Score Range 0-5; Min-Max score 0.8-6.0 Pain: Score Range 0-5; Min-Max score 0-6.0

  Based on The Female Sexual Function Index (FSFI) questionnaire

• Sexual function in non-obese women [ Time Frame: through study completion, an average of 6 months]

  A domain score of zero indicates that the subject reported having no sexual activity during the past month Desire: Score Range 1-5; Min-Max score 1.2-6.0 Arousal: Score Range 0-5; Min-Max score 0-6.0 Lubrication: Score Range 0-5; Min-Max score 0-6.0 Orgasm: Score Range 0 (or 1)-5; Min-Max score 0-6.0 Satisfaction: Score Range 0-5; Min-Max score 0.8-6.0 Pain: Score Range 0-5; Min-Max score 0-6.0

  Based on The Female Sexual Function Index (FSFI) questionnaire

• Sexual function in obese men [ Time Frame: through study completion, an average of 6 months]

  The possible scores for the IIEF-5 range from 5 to 25, and ED was classified into five categories based on the scores: severe (5-7), moderate (8-11), mild to moderate (12-16), mild (17-21), and no ED (22-25).

  Based on International Index of Erectile Function (IIEF) questionnaire

• Sexual function in non-obese men [ Time Frame: through study completion, an average of 6 months]

  The possible scores for the IIEF-5 range from 5 to 25, and ED was classified into five categories based on the scores: severe (5-7), moderate (8-11), mild to moderate (12-16), mild (17-21), and no ED (22-25).

  Based on International Index of Erectile Function (IIEF) questionnaire

• Evaluation of which nutrients the participants consume weekly [ Time Frame: through study completion, an average of 6 months]

  Mediterranean Diet Assessment Scale; It is a questionnaire consisting of 14 questions, including the type of essential oil used by the patients in meals, the amount of olive oil consumed daily, fruit and vegetable portions, margarine-butter and red meat consumption, weekly consumption of wine, pulses, fish-seafood, snacks, nuts, cake, olive oil tomato sauce consumption and whether white meat is preferred more than red meat. 1 or 0 points are taken for each question asked according to the amount of consumption, and the total score is calculated. A score of 7 and above indicates that the individual has an acceptable degree of adherence to the Mediterranean diet. A score of 9 and above shows that the individual strictly follows the Mediterranean diet.

  Based on Mediterranean Diet Assessment Tool

• Evaluation of which nutrients the participants consume weekly [ Time Frame: through study completion, an average of 6 months]

  The AHEI grades the diet, assigning a score ranging from 0 (nonadherence) to 110 (perfect adherence), based on how often eat certain healthy and unhealthy foods. For example, someone who reports eating no daily vegetables would score a zero, while someone who ate five or more servings a day would earn a 10. For an unhealthy option, such as sugar-sweetened drinks or fruit juice, scoring is reversed: a person who eats one or more servings would score a zero, and zero servings would earn a 10.
