Household cereal crop harvest and children’s nutritional status in rural Burkina Faso

Table 3 Adjusted estimates of differences in MUAC (mm) per specified difference in food energy production from crop harvest by sex

Sex	No. (%)	Mean MUAC, mm	Mean food energy from food crop harvest, kcal/ae/d	Difference in MUAC (95% CI): 3000 vs 1000 kcal/ae/d^a		Reduction in MUAC (95% CI) for a 1000 kcal/ae/d decline in crop harvest below 2900 kcal/ae/d^b:
Sex	No. (%)	Mean MUAC, mm	Mean food energy from food crop harvest, kcal/ae/d	Food crop harvest alone	Food & cash crop harvest combined	Food crop harvest alone	Food & cash crop harvest combined	p-value for interaction^c
All children	975 (100)	135	2978	2.49 (0.45, 4.52)	1.99 (0.27, 3.69)	1.29 (0.15, 2.42)	1.55 (0.30, 2.81)
Boys	499 (51)	136	3094	3.81 (0.84, 6.77)	3.47 (0.97, 5.96)	2.15 (0.49, 3.80)	2.43 (0.56, 4.30)	0.203
Girls	476 (49)	133	2842	0.99 (−1.81, 3.78)	0.86 (−2.13, 2.57)	0.42 (−1.14, 1.99)	0.69 (−1.02, 2.40)	0.203
