All references to the original sources are provided below.<br><b>CHILD OBESITY</b><br>Periodically, the English National Health Service (NHS) publishes statistics about various aspects of the health and habits of people living in England, including obesity. The NHS National Child Measurement (NCMP) measures the height and weight of children in Reception class (aged 4 to 5) and year 6 (aged 10 to 11), to assess overweight and obesity levels in children within primary schools. The program is carried out every year in England and statistics are produced at the level of Local Authority (that corresponds to Boroughs in London). We report the data for the school year 2015-2016 (file: <b>child_obesity_london_borough_2015-2016.csv</b>). For the school year 2013-2014, statistics in London are also available at ward-level (file: <b>child_obesity_london_ward_2013-2014.csv</b>)<br>The files are comma-separated and contain the following fields: <br><b>area_id:</b> the id of the borough<br><b>number_reception_measured:</b> number of children in reception year measured<br><b>number_y6_measured:</b> number of children in reception year measured<br><b>prevalence_overweight_reception: </b>the prevalence (percentage) of overweight children in reception year <b>prevalence_overweight_y6:</b> the prevalence (percentage) of overweight children in year 6<br><b>prevalence_obese_reception:</b> the prevalence (percentage) of obese children in reception year<br><b>prevalence_obese_y6:</b> the prevalence (percentage) of obese children in year 6<br><br><b>ADULT OBESITY</b><br><b><br></b>The<b> </b>Active People Survey (APS) was a survey used to measure the number of adults taking part in sport across England and included two questions about the height and weight of participants. We report the results of the APS for the year 2012. Prevalence of underweight, healthy weight, overweight, and obese people at borough level are provided in the file <b>london_obesity_borough_2012.csv</b>.<b><br></b>The file is comma-separated and contains the following fields: <br><b>area_id: </b>the id of the borough<b><br></b><b>number_measured: </b>number of people who participated in the survey<b><br></b><b><br></b><b>prevalence_healthy_weight: </b>the prevalence (percentage) of healthy-weight people<b><br></b><b>prevalence_overweight: </b>the prevalence (percentage) of overweight people<b><br></b><b>prevalence_obese:</b><b> </b>the prevalence (percentage) of obese people<b><br></b><br><b>BARIATRIC HOSPITALIZATION</b><b><br></b><br>The NHS records and publishes an annual compendium report about the number of hospital admissions attributable to obesity or bariatric surgery (i.e., weight loss surgery used as a treatment for people who are very obese), and the number of prescription items provided in primary care for the treatment of obesity. The NHS provides both raw counts at the Local Authority level and numbers normalized by population living in those areas. In the file <b>obesity_hospitalization_borough_2016.csv</b>, we report the statistics for the year 2015 (measurements made between Jan 2015 and March 2016).<br>The file is comma-separated and contains the following fields:<br><br><b>area_id: </b>the id of the borough<br><b>total_hospitalizations:</b> total number of obesity-related hospitalizations<br><b>total_bariatric:</b> total number of hospitalizations for bariatric surgery<br><br><b>prevalence_hospitalizations:</b> prevalence (percentage) of obesity-related hospitalizations <br><b>prevalence_bariatric:</b> prevalence (percentage) of bariatric surgery hospitalizations <br><br><b>DIABETES</b><br>Through the Quality and Outcomes Framework, NHS Digital publishes annually the number of people aged 17+ on a register for diabetes at each GP practice in England. NHS also publishes the number of people living in a census area who are registered to any of the GP in England. Based on these two sources, an estimate is produced about the prevalence of diabetes in each area. The data (file <b>diabetes_estimates_osward_2016.csv</b>) was collected in 2016 at LSOA-level and published at ward-level.<br><br>The file is comma-separated and contains the following fields:<br><b><br></b><b>area_id:</b> the id of the ward<br><b>gp_patients:</b> total number of GP patients <br><b>gp_patients_diabetes:</b> total number of GP patients with a diabetes diagnosis<br><b>estimated_diabetes_prevalence:</b> prevalence (percentage) of diabetes<br><b>AREA MAPPING</b><br>Mapping of Greater London postcodes into larger geographical aggregations.
