Brief Summary

Children who are overweight or obese can develop many health complications including diabetes, high blood pressure, high cholesterol and they break their bones more often than children who are of healthy body weights. Recent short-term studies in children suggest that increasing milk intake for 16 weeks begins to improve body composition and also reduces risk of developing diabetes. However, no study has been long enough to truly test for the benefits of high milk consumption on these conditions including bone. Both dietary and activity approaches to reducing obesity in children are suggested by health professionals and when combined are called lifestyle interventions. Therefore, McGill University has designed a 1-year intervention study focused on lifestyle improvements to reduce obesity in children 6 to 12 years of age. A control group will be monitored for the year, while two other groups will receive lifestyle interventions with standard recommended (2 servings a day) and high (4 servings a day) intakes of milk. The intervention will include 6 planning sessions to increase intakes of vegetables, fruits and milks along with more activity and less time watching television or using computerized games. Children will have muscle and fat measured using an x-ray device that also measures bone at the beginning, middle and end of the study. They will also have a small blood sample taken every 3 months to measure blood sugar, cholesterol and some nutrients. Changes over the study will demonstrate the benefits of lifestyle and milk interventions.

Outcome Measures

Primary Outcomes (1)

  • Body Composition

    Lean mass and fat mass will be measured using a Hologic 4500A dual x-ray absorptiometry machine (DXA). For this test, children will wear standardized clothing (pyjama bottoms and T-shirt). These measures are rapid, taking a total of 5 minutes x-ray time and the low radiation (\<10 uSV) will not exceed limits for x-ray exposure.

    Baseline and following 3, 6, 9 and 12 months of study participation.

Secondary Outcomes (3)

  • Blood Biochemistry

    Baseline and following 3, 6, 9 and 12 months of study participation.

  • Satiety Scores

    Following 12 months of study participation.

  • Bone Mass

    Baseline and following 3, 6, 9 and 12 months of study participation.

Study Arms (5)

Control 6-8 yrs

ACTIVE COMPARATOR

The group will receive information during the study about diet and exercise but will not receive the intervention till the end of the study protocol.

Behavioral: Control

2 servings dairy + exercise 6-8 yrs

EXPERIMENTAL

Subjects in this group will receive family based counseling to maintain the intake of 2 servings of dairy per day and also receive instruction on how to improve their physical activity.

Behavioral: 2 servings dairy + exercise

4 servings dairy + exercise 6-8 yrs

EXPERIMENTAL

Subjects in this group will receive family based counselling to maintain the intake of 4 servings of dairy per day and also receive instruction on how to improve their physical activity.

Behavioral: 4 servings dairy + exercise

4 servings dairy + exercise 9-12 yrs

EXPERIMENTAL

Subjects in this group will receive family based counselling to maintain the standard recommended intake of 4 servings of dairy per day for 9-14 year olds according to the Canada's Food Guide and also receive instruction on how to improve their physical activity.

Behavioral: 4 servings dairy + exercise

Control 9-12 yrs

Eligibility Criteria

Age6 Years - 12 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Participants must be between 6 and 12 years of age at onset of the intervention
  • Consume \< 2 servings of milk and milk products but be receptive to the recommendations
  • Have body mass index (BMI) over the 97 percentile for age and sex according to the World Health Organization. The Canadian Community Health Survey (CCHS)assessment of obesity used the definition by the International Obesity Task Force. This yields similar results as when using BMI percentile cut-offs proposed by the World Health Organization (WHO) for all ages of children. The WHO now has reference data available to 19 years of age. The BMI values at the 97th percentile are lower compared to the 2000 Centres for Disease Control charts (http://www.who.int/growthref/who2007\_bmi\_for\_age/en/index.html).

You may not qualify if:

  • Known or suspected serious, chronic illness of childhood, such as cancer, Crohn's disease, nephrotic syndrome, rheumatic conditions, and diabetes, etc., or those with disturbances in bone, vitamin D or mineral ion metabolism including rickets, osteomalacia, liver disease, renal disease, immobilization (complete or partial), current fractures, and disorders of the parathyroid gland.
  • Use in the past 3 months, medications known to affect bone and/or mineral ion metabolism including all glucocorticoids, phosphate therapy or vitamin D analogues and any bisphosphonates.
  • Severe anemia precluding blood sampling (previously diagnosed).
  • Established diabetes mellitus (any type). Use of a glucometer and finger lance will confirm.
  • Hyperlipidemia ascribed to non-dietary causes.
