Table 4 Factors associated with fully support^# to biobanking of rDBS for medical secondary use

	Fully support^# to biobanking of rDBS		RR^ for strong support to biobanking of rDBS (95%CI)
	Yes N = 214	No N = 787	RR^ for strong support to biobanking of rDBS (95%CI)
Mother	83%	86%	0.68* (0.49, 0.94)
Age (mean ± SD)	33.7 ± 4.8y	33.9 ± 6.2y	0.99 (0.97, 1.02)
Non-Hong Kong born	44%	27%	1.73* (1.33, 2.24)
University degree or above	41%	46%	0.94 (0.72, 1.25)
Household income of HKD80000 or above	12%	12%	1.03 (0.68, 1.56)
No Religion	66%	69%	0.79 (0.61, 1.02)

^#Fully support from parents when being asked on their thoughts about having their child’s rDBS being stored in a national biobank (n = 214, 21%) compared to the rest (n = 787) consisting of 52% supported but indicated some concerns, 21% inclined to reject and 6% strongly opposed the idea of biobanking
^RR (relative risk) > 1.00 indicates the factor is associated with a greater support to biobanking of rDBS; RR < 1.00 indicates lower support
*p < 0.05; ⁺0.05 < p < 0.1
