Increase in body weight over a two-year period is associated with an increase in midfoot pressure and foot pain

Table 4 Multivariable linear regression between change in peak plantar pressure and change in foot pain^a

Region	Pain intensity	p value	Functional limitation	p value
Whole foot	1.405 (−0.237 to 3.047)	0.092	3.446 (−0.510 to 7.401)	0.086
Heel	1.831 (0.540 to 3.121)	0.006	4.054 (0.898 to 7.210)	0.013
Midfoot	1.913 (0.392 to 3.434)	0.015	4.505 (0.825 to 8.186)	0.018
Forefoot	1.450 (−0.087 to 2.987)	0.064	3.184 (−0.548 to 6.915)	0.093
Hallux	−0.352 (−1.945 to 1.241)	0.672	1.120 (−2.716 to 4.956)	0.560
Lesser toes	0.623 (−1.309 to 2.556)	0.520	2.530 (−2.092 to 7.151)	0.276

Each region and pain subscale was analysed independently. Change in foot pain intensity and functional limitation units are Manchester Foot and Disability Index Rasch transformed scores (pain intensity and functional limitation domains)
Values are unstandardised B coefficients (95% confidence interval)
^aAdjusted for age, gender and change in contact time
