Abstract

Background Coronary heart disease (CHD) risk factors increase with age and body mass index (BMI; in kg/m2). However, whether lifestyle intervention ameliorates metabolic CHD risk factors in obese older adults is unknown.Objective The objective was to determine whether lifestyle intervention improves metabolic CHD risk factors in obese older adults.Design A 6-mo outpatient randomized controlled trial was conducted in obese (BMI >or= 30) older (>or=65 y) adults randomly assigned to diet and exercise therapy (treatment group; n = 17) or no therapy (control group; n = 10). The main outcomes were CHD risk factors.Results Body weight decreased by 8.4% (8.2 kg) in the treatment group; weight did not change significantly (0.7 kg) in the control group (P < 0.001 between groups). Changes between the control and treatment groups, respectively, in waist circumference (1 and -10 cm), plasma glucose (4 and -4 mg/dL), serum triacylglycerols (0 and -45 mg/dL), and systolic (-2 and -10 mm Hg) and diastolic (0 and -8 mm Hg) blood pressure were different (P < 0.05 for all). The number of subjects with the metabolic syndrome decreased by 59% in the treatment group but did not change significantly in the control group (P < 0.05). Serum free fatty acids increased by 10 micromol/L in the control group and decreased by 99 micromol/L in the treatment group (P < 0.05). Changes between the control and treatment groups, respectively, in C-reactive protein (0.8 and -2.5 mg/L) and interleukin 6 (1.6 and -2.4 pg/mL) were different (P < 0.05 for both).Conclusions Lifestyle intervention decreases multiple metabolic CHD risk factors simultaneously in obese older adults.

  • In response to a 6-month randomized diet and exercise intervention, levels of C-reactive protein and IL-6 decreased in older adults (age ≥65 years) with obesity (BMI ≥30 kg/m2) compared with controls (−2.5 versus 0.8 mg/l (P < 0.05) and −2.4 versus 1.6 pg/ml (P < 0.05), respectively).

    “levels of C-reactive protein and IL-6 decreased in older adults (age ≥65 years) with obesity (BMI ≥30 kg/m2) compared with controls (−2.5 versus 0.8 mg/l (P < 0.05) and −2.4 versus 1.6 pg/ml (P < 0.05), respectively)300”
  • One randomised controlled trial demonstrated improved cardiometabolic risk markers in older adults losing 8% body weight from baseline with energy-restriction and exercise versus placebo.

    “One RCT demonstrated improved cardiometabolic risk markers in older adults losing 8% body weight from baseline with energy-restriction and exercise (vs. placebo) [61].”
  • Many studies have shown that weight loss improves blood pressure, diabetes, sleep apnea, hyperlipidemia, and sympathetic/parasympathetic tone.

    “Many studies have shown that weight loss improves blood pressure, diabetes, sleep apnea, hyperlipidemia, and sympathetic/parasympathetic tone (196, 284, 324, 365).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
