AB  - OBJECTIVE: To investigate if socioeconomic gradients in health reduce during 
      adolescence (the equalisation hypothesis) in four low-income and middle-income 
      countries (LMIC). SETTING: Analysis of the Young Lives Study cohorts in Ethiopia, 
      Peru, Vietnam and India. PARTICIPANTS: A total of 3395 participants (across the 
      four cohorts) aged 6-10 years at enrolment and followed up for 11 years. OUTCOMES 
      MEASURED: Change in income-related health inequalities from mid-childhood to late 
      adolescence. Socioeconomic status was determined by wealth index quartile. The 
      health indicators included were self-reported health, injuries in the previous 4 
      years, presence of long-term health problems, low mood, alcohol use, 
      overweight/obesity, thinness and stunting. The relative risk of each adverse 
      health outcome between highest and lowest wealth index quartile were compared 
      across four waves of the study within each country. RESULTS: We found steep 
      socioeconomic gradients across multiple health indicators in all four countries. 
      Socioeconomic gradients remained similar across all waves of the study, with no 
      significant decrease during adolescence. CONCLUSION: We found no consistent 
      evidence of equalisation for income-related health inequalities in youth in these 
      LMIC. Socioeconomic gradients for health in these cohorts appear to persist and 
      be equally damaging across the early life course and during adolescence.
