Social Engagement and Network Initiatives for Older Relief Act or the SENIOR ActThis bill expands the scope of authorized&nbsp;Administration on Aging (AOA) grants to include&nbsp;services addressing loneliness in older individuals (i.e., aged 60 or older), and requires a report evaluating whether certain federal programs are adequately addressing this topic.Under current law, the&nbsp;AOA provides grants to states for disease prevention and health promotion services for older individuals, including services addressing the negative health effects of social isolation.&nbsp;The bill expands the scope of the services eligible for&nbsp;these grants to include services addressing the negative health effects of loneliness.Also, the bill requires the Department of Health and Human Services to submit to Congress a report (1)&nbsp;evaluating whether its programs for older individuals&nbsp;are adequately addressing loneliness,&nbsp;and (2)&nbsp;recommending measures for reducing the negative health effects of loneliness and fostering multigenerational family connections.&nbsp;
