From: Does income have a non-linear impact on residents鈥� BMI? Re-examining the obesity Kuznets curve
The difference in age for the effect of income on BMI. Note: In order to visually reflect the impact of income on BMI, we did not consider other variables and only plotted the graph using the coefficients of income and income squared in the regression. The inflection point for residents aged 50鈥�65 years is 47 979 yuan, whereas the inflection points for the other two groups are approximately 45,000 yuan
