Cytokine and Body Composition's Changes in Overweight/Obese Women
This trial is active, not recruiting.
|Conditions||maternal obesity complicating pregnancy, exercise addiction, high-risk pregnancy, inflammatory status during preganancy, maternal body composition|
|Treatment||lifestyle change program|
|Sponsor||University of Modena and Reggio Emilia|
|Start date||January 2015|
|End date||April 2016|
|Trial size||59 participants|
|Trial identifier||NCT02766426, 136/15|
Sincev the adipose tissue as been identified as a metabolic active tissue that produces and regulates pro-inflammatory factors, the investigators studied the relationship between cytokine changes and maternal body composition.
The investigators evaluated plasmatic pro- and anti-inflammatory cytokines levels in pregnant women with BMI >25 Kg/m^2 undergoing a lifestyle change program, and if this is related with changes in body composition.
Women enrolled in the study were provided nutritional advices about lifestyle: a proper nutrition and a constant physical activity (30 minutes/day, 3 times/week, according to the American College of Obstetricians and Gynecologists Guidelines) in an integrated counselling with a dietitian and a gynaecologist, both attendant since the enrollment.
Plasma pro- and anti-inflammatory markers were investigated at enrollment (9-12 weeks) and at 36-38 weeks.
Furthermore, the investigators used the bioimpedance analyzer to evaluate changes of body composition (i.e. fat mass and fat free mass) at first and third trimester.

|Official title||Cytokine and Body Composition's Changes Throughout Pregnancy in Overweight/Obese Women Undergoing an Early Lifestyle Change Program|
|Description||Pregnant women, recruited from antenatal clinics, with pre-pregnancy BMI ≥ 25 kg/m2, age >18 years and singleton pregnancy were enrolled within 12th week at the Obstetric Unit of Policlinico Hospital of Modena. Exclusion criteria were as follows: twin pregnancies, chronic diseases (i.e., diabetes mellitus, chronic hypertension, untreated thyroid diseases) and dietary supplements or herbal products known to affect body weight, other medical conditions that might affect body weight. At the first visit, an accurate obstetric history, family history, and personal history was collected for the assessment of exclusion criteria. The blood pressure, height and weight were measured, and the BMI is calculated. Eligible women were given nutritional advices about lifestyle and physical activity, in agreement with the Italian Guidelines for a healthy diet during pregnancy. The diet given comprised 1500 kcal/day and consisted of 3 main meals and 3 snacks (breakfast, snack, lunch, snack, dinner, and evening snack) that corresponds to the baseline metabolism of a pregnant woman. In view of the physical activity program, the dietitian added an amount of 200 kcal/day for obese or 300 kcal/day for overweight women. The exercise intervention was focused on increasing walking and developing a more active lifestyle (i.e., walking rather than driving for short distances). The recommended exercise prescription for pregnant women was generally consistent with recommendations for the general adult population. All participants were advised to participate in 30 min of moderate intensity activity at least 3 days a week. Each subject taking part at the study received a 75-g 2-h Oral Glucose Tolerance Test (OGTT) at 16-18 and/or 24-28 weeks. The diagnosis of gestational diabetes mellitus was made for any glucose value exceeding the normal cut-off, as reported by the Guidelines. If OGTT is pathological, women are referred to other health care specialists for further clinical evaluation and/or specific treatment. Women were scheduled to have a specific follow-up visits for adherence to the program at 16th, 20th, 28th and 36th week also evaluating the fat mass, fat-free mass and total body water through the use of the bioimpedance analyzer. Furthermore, at baseline and at 36-38 week, blood plasma samples were collected in order to investigate: plasma pro- and anti-inflammatory markers related to obesity and to visceral adipose tissue (interferon-γ, interleukin-1α, interleukin-1β, interleukin-2, interleukin-4, interleukin-6, interleukin-8, interleukin-10, interleukin-12p70, and tumor necrosis factor-α). Data regarding pregnancy and delivery were collected from clinical diaries.|
