“…A higher frequency of contacts and extended duration of treatment has been reported to result in better sustained weight losses. 6,28 The lack of protocolled follow-up visits was a characteristically feature in our study population.…”

“…This will intensify the contact between caregivers and patients which is known to affect the outcome. 5,6 After verification of the addresses patients and general practitioners received a letter explaining the aim and setup of the study and a telephone call 2 weeks later to make the appointment for the visit at home. Subjects who disliked a visit at home but were willing to fill out the forms were contacted by mail.…”

“…Intensification of contacts with care-givers has been shown to improve the outcome, at least in the short-term. 5,6 Clinical trials may, therefore, not reflect the everyday routine practice and outcomes from trials may not be extrapolated to patients, devoid of a protocol-wise follow-up. Many subjects do not respond to an invitation to visit the outpatient clinic in the years after the first year of operation and certainly not when more than 5 years have passed since the operation.…”

Objective: Obesity management is focused at weight loss to obtain health, psychological and social benefits. Outcomes from controlled trials, however, do not reflect the everyday routine practice. Therefore, we aimed to investigate the results from surgically induced weight loss in patients devoid of a protocol-wise follow-up, who were visited at home. Patients and methods: Patients who underwent a vertical banded gastroplasty or a gastric bypass between 1980 and 1997 were eligible. Body weight and height were measured. Patients filled out questionnaires on health status (Nottingham Health Profile (NHP)), psychological symptoms (Symptom Check List (SCL-90-R)), personality traits (Dutch Personality Questionnaire (DPQ)) and eating behaviour (Dutch Eating Behaviour Questionnaire (DEBQ)). Results: Out of 451 operated patients the addresses of 313 subjects could be traced and 236 (75%) agreed to participate. They maintained a mean (s.d.) loss of 32.1 (22.6) kg and 45.2 (29.3) % of excess weight, 8.2 (4.5) years after the operation, about two-third of the largest weight loss they achieved after 17 months postoperatively. The NHP and SCL-90-R conformed to norm values in males except for energy, sleep and emotional reactions. Females differed from norm values in every aspect and even women achieving a BMIo30 kg/m 2 did not catch up to norm values. Weight loss was inversely related to physical immobility and pain. Personality traits (DPQ) showed a higher grievance and dominance and a lower rigidity and self-esteem compared to norm values. Females scored higher in inadequacy and lower in social inadequacy. Eating patterns (DEBQ) showed mainly emotional eating and restrained eating. Effect sizes of X0.8 s.d. were chosen to reflect the clinical relevance of statistically significant findings. Pain, disturbances in sleep, energy and mobility and emotional and restrained eating proved to be clinically relevant. In subjects operated 45 years ago, a higher sensitivity, a higher inadequacy and a lower social inadequacy were observed compared to more recently operated subjects. A more restrained eating pattern was related to an operation of recent date. Conclusions: Surgically induced weight losses are satisfactory in the long-term, even in patients not attending a strict follow-up protocol. Health, psychological symptoms, personality traits and eating behaviour were related to weight loss and time lapse since the operation and did not return to reference normal-weight subject values.

“…These positive findings may be reflective of the large initial weight losses (16 kg) and the length of treatment, which on average consisted of weekly meetings for 1 year with the majority of that time being focused specifically on weight maintenance. It is well established that longer treatments lead to better long-term results, 26,27 particularly if maintenance treatment involves frequent self-monitoring and positive reinforcement 23 or effective problem-solving therapy. 28 Our results suggest that an extended weight loss maintenance treatment may be effective for not only decreasing weight regain during treatment, but also within the 1-2 years after contact with the treatment program ends.…”

Weight maintenance, behaviors and barriers among previous participants of a university-based weight control program

Objective: To examine weight loss maintenance among previous participants of a university-based behavioral weight management program and to compare behavioral strategies and perceived barriers between successful and unsuccessful maintainers. Method: Previous program participants (n ¼ 179) completed mailed surveys assessing current weight, weight control behaviors and perceived barriers to weight loss maintenance. Results: At 14.1 ± 10.8 months following completion of treatment, survey respondents were on average 12.6 ± 12.6 kg, or 11.3±10.7%, below baseline weight; 76.5% of respondents had successfully maintained weight, defined as maintaining a weight loss of at least 5% below baseline. Compared to unsuccessful maintainers, successful maintainers reported practicing four dietary and three physical activity weight control strategies more often and experiencing five barriers to healthy eating and exercise less often. After accounting for time since treatment and maximum weight loss while in treatment, the strongest correlates of successful weight loss maintenance were frequent exercise and perceived difficulty of weight management. Conclusions: Clinically meaningful weight loss maintenance was achieved by the majority of participants. Findings support the literature indicating that physical activity is one of the strongest predictors of successful weight loss maintenance. Findings also suggest that strategies to reduce the level of perceived effort required for long-term weight control may improve maintenance outcomes.

“…Standard behavioral treatments for obesity commonly prescribe a moderate caloric restriction, prescribing an intake of 1000 -1200 kcal/day (NHLBI, 2000;Perri, Nezu, Patti, & McCann, 1989) as well as certain standard methods for weight loss.…”

ABSTRACTTraditional obesity treatments have demonstrated successful short-term, but not long-term, weight loss. Behavior Therapies (BT) typically prescribe moderate kilojoule reduction and eating rules that promote a "dieting mentality." Behavioral Choice Treatment (BCT), which emphasizes mild kilojoule reduction and flexibility in eating has previously demonstrated greater weight loss maintenance compared to BT. This study compares eating patterns across treatments to explore differences related to weight loss. intake. No group differences were found for meal frequency or variability in kilojoule intake. These data suggest slight rather than moderate caloric restriction and greater flexibility in eating may promote the observed long-term weight management in BCT over BT. iv
