Relationship between calibrated energy intake and daily step counts using a restricted cubic spline model among older adults. (A) crude model and (B) multivariable adjusted model in 2,107 men and (C) crude model and (D) multivariable adjusted model in 2,011 women. Because the data were sparse, we truncated the analysis at 12,000 steps/day (99% of the distribution). Solid and dashed lines represent mean calibrated energy intake and 95% confidence intervals, respectively. The adjusted factors were age, population density, season of wear, body mass index, smoking status, alcohol consumption status, family structure, educational attainment, economic status, denture use, medication use, number of chronic diseases, and frailty status
