Joint Strategic Needs Assessment

Start Well

What happens in pregnancy, childhood and adolescence impacts on physical and emotional health all the way through to adulthood. Where our children live, their household income and how they are cared for all impact the health and wellbeing of our children.

There are 20,050 children aged under 16 living in our borough. Of these, 6,400 are aged under five. 44% of children and young people are from a Black, Asian or other ethnic minority background.

In Kensington and Chelsea, over 1 in 4 children are living in poverty, and there are 106 looked-after-children. Almost 1 in 3 children are overweight by the time they leave primary school, and 1 in 5 are affected by mental health problems. Working with our communities to design preventative activities and promote healthier lifestyles is key to ensuring we give our children the best start in life.

"It’s good for us to socialise as communities, our kids have become too used to using their screens during lockdown, they are more isolated. We need more group and physical activities for kids."

Childhood vaccinations

For all types of childhood vaccinations, uptake is below the 95% target to stop the spread and protect the community.

Children are of greater risk of developing complications if they catch flu. Uptake of flu vaccinations in schools increased compared to the previous year (this year about 2 in 5 children in primary school and 1 in 4 in secondary school received the vaccination). Teenage vaccination uptake is among the lowest in England, including vaccination against cervical cancer and meningitis and sepsis.

Dental health

1 in 4 five-year-olds have decayed teeth.

By the age of five, 1 in 4 five-year-olds have one or more decayed, filled or missing teeth (24%). It is a common cause of hospital admission, and children who have toothache may experience pain, have difficulties with eating, sleeping and socialising and may have to be absent from school. 1 in 3 children have seen a dentist in the past year.

Young people and mental health

1 in 5 children and young people have mental health needs.

In 2023, an NHS survey estimated that 21% of eight to 25-year-olds in England have a mental health need - equivalent to 6,900 people in Kensington and Chelsea.

While survey data of self-reported need has been static, service use has been on an upward trajectory, stabilising over the last couple of years. This would suggest that the proportion of children with mental health needs that are getting support is increasing.

Childhood obesity

Almost 1 in 3 children are overweight by age 11.

23% of children are overweight or obese when they enter primary school. This rises to 32% of children aged 10 and 11 leaving primary school. This varies by ward; for example those living in Ladbroke Grove are three times more likely to be overweight than those living in Notting Hill South. Children whose parents are obese are more likely to be obese themselves. This highlights the complexity of supporting families to maintain or reach a healthy weight. Being an unhealthy weight is more likely in boys who identify themselves as being from Black, Mixed or Other ethnic groups at age 10-11.

Education

Education creates opportunities for better health.

We have some of the highest levels of outstanding schools in London, although over a quarter of our children live in poverty, and 4,676 children are eligible for free school meals. Education can trigger healthier futures and protect against disadvantages in later life. 70% of children had a good level of development at the end of reception year, and 61% of children achieved nine to five in GCSE English and Mathematics (76% achieving nine-four). The average attainment eight score was 54.3. The average GCSE level of attainment is the lowest in the most deprived areas. Just over 4% of children have an education, health and care plan and 14.1% of children receive special educational needs support.
