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

Table 3 Multivariable linear regression between change in body weight with change in regional peak plantar pressure and change in foot pain

i) Plantar pressures^a	Unstandardised B coefficients (95% CI)	p value
Whole foot	2.151 (−2.275 to 7.186)	0.302
Heel	2.921 (−0.940 to 6.782)	0.135
Midfoot	4.648 (0.273 to 9.024)	0.038
Forefoot	2.230 (−2.231 to 6.691)	0.319
Hallux	1.444 (−3.046 to 5.935)	0.521
Lesser toes	4.303 (−1.032 to 9.638)	0.111
ii) Manchester Foot Pain and Disability Index^b
Pain intensity subscale	0.216 (−0.611 to 1.044)	0.601
Functional limitation subscale	0.409 (0.101 to 0.717)	0.010

Each region and pain subscale was analysed independently. The change in foot pain intensity and functional limitation units are Manchester Foot and Disability Index Rasch transformed scores (pain intensity and functional limitation domains)
Abbreviation: CI confidence interval
^aAdjusted for age, gender and change in contact time
^bAdjusted for age and gender
