[Question] Is preventing child abuse a plausible Cause X?

To­day I’m flip­ping through The Body Keeps Score, a pop sci re­view of the aca­demic re­search on trauma to date.

I was quite sur­prised by this pas­sage, on p. 150 of my copy:

The first time I heard Robert Anda pre­sent the re­sults of the ACE study, he could not hold back his tears. In his ca­reer at the CDC he had pre­vi­ously worked in sev­eral ma­jor risk ar­eas, in­clud­ing to­bacco re­search and car­dio­vas­cu­lar health.
But when the ACE study data started to ap­pear on his com­puter screen, he re­al­ized that they had stum­bled upon the gravest and most costly pub­lic health is­sue in the United States: child abuse.
[Anda] had calcu­lated that its over­all costs ex­ceeded those of can­cer or heart dis­ease and that erad­i­cat­ing child abuse in Amer­ica would re­duce the over­all rate of de­pres­sion by more than half, al­co­holism by two-thirds, and suicide, IV drug use, and do­mes­tic vi­o­lence by three-quar­ters. It would also have a dra­matic effect on work­place perfor­mance and vastly de­crease the need for in­car­cer­a­tion.

Essen­tially, the ACE study seems to demon­strate that child­hood trauma is up­stream of a wide va­ri­ety of bur­den­some prob­lems.

Seems plau­si­ble that there are tractable in­ter­ven­tions that re­duce the effects & in­ci­dence of child­hood trauma. Also the area seems ne­glected (con­tin­u­ing from p. 150):

When the sur­geon gen­eral’s re­port on smok­ing and health was pub­lished in 1964, it un­leashed a decades-long le­gal and med­i­cal cam­paign that has changed daily life and long-term health prospects for mil­lions. The num­ber of Amer­i­can smok­ers fell from 42 per­cent of adults in 1965 to 19 per­cent in 2010, and it is es­ti­mated that nearly 800,000 deaths from lung can­cer were pre­vented be­tween 1975 and 2000.
The ACE study, how­ever, has had no such effect. Fol­low-up stud­ies and pa­pers are still ap­pear­ing around the world, but the day-to-day re­al­ity of… the chil­dren in out­pa­tient clinics and res­i­den­tial treat­ment cen­ters around the coun­try re­mains vir­tu­ally the same.

Has any­one looked into this?
