A Pilot Study Evaluating a Clinically Managed Weight Loss Program

A Pilot Study Evaluating the Clinically Managed Weight Loss Program at the Wellness Institute at Seven Oaks General Hospital

This is a pilot study evaluating a clinically managed weight loss program. The program consists of a 17-week weight loss program which involves a multidisciplinary team where personalized interventions are given to participants from the team based on the participants goals.

The clinically managed weight loss program is managed by a clinical team including a Program Manager, Registered Dietitians, Canadian Society of Exercise Physiology-Certified Personal Trainers, Clinical Psychology Associate or Cognitive Behavioural Therapist, and a Physician. The team will collaborate together to prescribe a plan best suited for the participants' needs with the focus on lifestyle changes, such as, sleep, mental health, and behaviours. Outcome measures will be collected as part of the pilot study, such as, anthropometric measurements and body composition, cardiovascular assessment, clinical chemistry, physical activity, nutrition, and behaviour and health screening questionnaires.

There are three components of the intervention, this includes: psychology, nutrition, and physical activity. For the psychological portion, a therapist will assess the participant at baseline to determine if there are barriers associated with making lifestyle changes. For nutrition, the dietitian will assess the participant and create a meal plan based on their nutritional needs and guide the participant to reaching their nutritional goals. The psychological and nutrition portion may be interchangeable depending on the participants needs. For physical activity, the personal trainer will assess the participant and create an exercise plan that consists of resistance training and weight bearing exercises suitable for the participant while also guiding the participant to reach their exercise goals.

Quality of life will be measured through the SF-36 quality of life questionnaire. The SF-36 measures nine areas: physical functioning, role functioning (emotional), role functioning (physical), energy/fatigue, emotional well-being, social functioning, pain, general health, and health change. A higher score indicate greater levels of quality of life.

Sleep will be measured through the Pittsburgh Sleep Quality Index questionnaire. The Pittsburgh Sleep Quality Index questionnaire measures the quality and pattern of sleep in adults, and includes seven components: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medications, and daytime dysfunction. A score of 5 or less is indicated as good sleep quality where a score of 6 or more is indicated as poor sleep quality.

Attendance will be measured by checking if participants have attended each appointment with the health care professional as implemented by the program.

Intervention adherence will be measured by checking if participants have attended each appointment with the health care professional as implemented by the program. If the participant has attended 80% or more of their appointments, this would be classified as good intervention adherence to the program.

Waist circumference in cm will be measured in triplicate, to the nearest 0.1 cm at the umbilicus, between the last rib and iliac crest using a fibreglass tape measured by an exercise professional.

The InBody 570 Body Composition Analyzer will measure body fat percentage by bioelectrical impedance.

The InBody 570 Body Composition Analyzer will measure lean mass percentage by bioelectrical impedance.

Systolic blood pressure in mmHg is measured in triplicate, on the non-dominant arm in a sitting position by an exercise professional using a validated oscillometric blood pressure monitor.

Diastolic blood pressure in mmHg is measured in triplicate, on the non-dominant arm in a sitting position by an exercise professional using a validated oscillometric blood pressure monitor.

Heart rate in beats per minute is measured in triplicate, on the non-dominant arm in a sitting position by an exercise professional using a validated oscillometric blood pressure monitor.
