Abstract

FREEDSON. Improved psychological well-being, quality of life, and health practices in moderately overweight women participating in a 12-week structured weight loss program. Obes Res. 1998;6:208-218. Objective: To study the effects of a 12-week weight loss strategy involving increased physical activity, self-selected hypocaloric diet, and group support on psychological wellbeing, quality of life, and health practices in moderately obese women. Methods; Eighty women aged 20--49 years weighing between 20-50% above 1983 Metropolitan Life Insurance Tables were randomly assigned to a weight loss intervention (6279 kJ/week of physical activity, 33,258--41,462 kJ/week diet and weekly'rneetings) or served as controls. Subjects were tested pre and post 12-weeks. Results: The intervention group lost significant (p<O.OOl) body weight (kg) and body fat (%) compared to controls (-6.07 ± 4.01 kg vs. 1.31 ± 1.28 kg; 36.8%-32.5% vs. 36.2%-36.0%). Intervention subjects vs. controls achieved significant improvements (p<O.OOl) in body cathexis (X Change 18.6 ± 16.7 vs. 0.7 ± 8.6) and estimation of ability to achieve physical fitness (X Change 8.1 ± 7.1 vs.

Health-related quality of life in WHO Class II–III obese men losing weight with very-low-energy diet and behaviour modification: a randomised clinical trial

“…13 The positive changes in mental HRQOL have been related to the magnitude of weight loss and the duration of follow-up, with some tendency for the scores to return towards baseline levels in subjects with less than a 20 kg weight loss at a 2 y followup. 18 The two previous randomised trials by Rippe et al 25 and Fontaine et al 26 showed improvement on mental health and vitality among obese women losing weight. In our study among men, there were transient improvements in the mental health scales of RAND-36 during treatment.…”

“…Fontaine et al 26 had a 13-week trial comparing lifestyle physical activity with traditional aerobic physical activity showing improvement in physical functioning, physical role functioning, general health, vitality, social functioning and mental health, but no between-group differences in weight loss or HRQOL responses. Rippe et al 25 randomised 80 women into a 12-week weight loss group and a control group. The intervention group showed increased physical functioning, vitality and mental health.…”

“…18 -24 Two short-term randomised weight loss trials with lifestyle intervention have shown improvements in HRQOL. 25,26 The duration of these studies was only 12 -13 weeks and there was no follow-up after the intervention; the longer-term effects of non-surgical weight loss interventions on HRQOL have not been studied.…”

Associação entre atividade física e qualidade de vida em adultos

“…4,19,26,31,39,51 Studies have investigated the association between PA and overall QoL, and the effects of PA on specifi c domains of QoL, 4,37 and it has often been reported an association with the "physical" and "mental" domains. 19,39,41,42,46,51 Evidence supports a positive association between PA and QoL, but the state of the art is not well established. The magnitude of this association is confl icting in different populations 4,37 and inconsistent results have been found when instruments for measuring PA and QoL, as well as designs, were compared.…”

Health-related quality of life in obese outpatients losing weight with very-low-energy diet and behaviour modification—a 2-y follow-up study

“…[21][22][23][24][25][26][27] The previous weight loss studies with lifestyle intervention have shown various improvements in HRQL, but the studies have usually been very short in duration. [28][29][30][31] Studies with longer follow-up have shown a more modest improvement in HRQL, 32 and to our knowledge there are no reports of follow-up over 1 y.…”
