Table 3. Study findings on Demographic Differences.

Group	Indicative of Negative Attitude	Indicative of Positive Attitude
Age	Compared to those aged 25–34, respondents between the ages of 35–64 were more likely to report they would be worried about the security of their records as part of a national EHR 36.	Increase in age by each 10 year increment was significantly associated with an increased likelihood of reporting that any info can be provided to researchers without asking for consent 24.
	Compared to those aged 25–34, respondents over 35 years old were more likely to report less confidence in the ability of NHS security and were less likely to report that EHRs were equally or more secure than paper records 36.	Older people (55–64, 65+) were more likely to find a drug company conducting research into the unwanted side effects of a drug using deidentified data to be more acceptable than younger people (16–24, 25–34, 35–44, 45–54) 33.
	Older people were increasingly more likely to report that they would not be in favour of a national EHR compared with 25–34 year olds 35.	Those aged 55–64 tended to agree that research should be conducted by commercial organisations if there is a possibility of new treatments being discovered in comparison to 16–24s and 35–44s 33.
		In the general public, support for the opt-out collection method was higher in over 55s (58%) than 18–34 (49%) and 35–54s (49%) 32. Those over 55 were more likely to say to say that they would allow their data to be used for medical research compared to those aged 16–24 31.
Education	Respondents with lower educational qualifications were more likely to expect to be asked for explicit consent before their deidentified records were accessed 37.	Compared with participants with higher degrees, individuals with no academic qualifications were less likely to say that they would worry about security if their record was part of a national EHR 36.
		Compared with completion of third level education, completion of only primary level education was associated with increased likelihood of reporting that any info can be provided to researchers without asking for consent 24.
Socioeconomic Status	Those of a lower socioeconomic status were more likely to be concerned about privacy 23.	Those in the lower socioeconomic group DE (43%) were more likely to support companies using health data collected in the NHS to help target health products at different groups of people 33.
	Those in socioeconomic groups C2 and DE were less likely than those in AB and C1 to view the use of health data as having a potential benefit to society 26.
	Those in the lower socioeconomic group DE were less likely to say they trusted a variety of people with their health data; say that the advantages outweigh the disadvantages of using health data in research; and say that researcher can use data without prior consent than ABs 31.
	Those in socioeconomic groups C1 and C2 were less likely than ABs to allow their health data to be used 31.
	Those in socioeconomic groups DE (46%) were less likely to support commercial organisations to undertaking health research with health data than AB (62%) 33.	Those in socioeconomic groups DE (26%) were less likely to support commercial organisations to undertaking health research with health data than AB (30%) 33.
Ethnicity	Black British respondents were more likely to say they would not support the development of a national EHR system compared with White British respondents 35.	Compared with White British groups White non-British, Asian, British Asian, Black-African, Caribbean, and British Black groups were more likely to say that EHRs are as secure, or more secure that paper records 36.
	Respondents identifying as belonging to an ethnic group other than White British were more likely to expect to be asked for explicit consent before their deidentified records were accessed 37.
	Those whose ethnicity was not White British were more likely to be concerned about the invasion of privacy 23.
