The figures, from the Scottish Government, show more than a quarter of the children helped are in the Greater Glasgow area.
The healthy weight interventions are carried out on children who are clinically overweight, obese and severely obese.
In the NHS Greater Glasgow and Clyde area there were 1187 interventions last year where obese children attended sessions, a slight increase on the 1134 for 2012.
In response to concerns about rising childhood obesity, the Government issued targets for health boards to ensure as many overweight children as possible were given assistance with diet and exercise.
Greater Glasgow has set a goal of helping 3389 kids by March next year and in the first two years of a three-year programme, achieved almost 70% of that target.
Across Scotland the target is to help almost 15,000 children and up to the end of March this year 10,183 interventions had taken place.
The report stated: "There is continuing concern over the levels of overweight and obesity among children in Scotland.
"Obesity in childhood is a health concern in itself, but can also lead to physical and mental health problems in later life, such as heart disease, diabetes, osteoarthritis, back pain, increased risk of certain cancers, low self esteem and depression."
This week the Evening Times reported on how a mobile gym was being used to help children as young as three lose excess weight.
Before the six-week programme the youngsters' Body Mass Index (BMI) averaged at 18.5, which is in the overweight category.
Afterwards it was still overweight but had reduced to 17.9.
Government guidance for the healthy weight interventions includes a target that at least 40% should target children living in the most deprived communities.
In Greater Glasgow more than half of those included in the programme were from the most deprived areas.
Initially the programme was for children aged between five and 15, but it has since been extended to take in pre-school children from age two upwards.
The interventions can either be for individual children or whole school classes.
