Which ones are correct?

Historians have raised a number of issues concerning the emergence of modern anorexia nervosa, which was a trans-Atlantic phenomenon involving both the United States and Western Europe from the mid-nineteenth century onward. The basic issues involve sorting out the disease from its specific historical cause–why the disease emerged when it did– and the fact that it appears so disproportionately in females. The first cases of the modern disease occurred before thinness was widely fashionable,in middle-class families where some young women chose food refusal as a method of rebellion that could not be explicitly articulated. Obviously, the rise of concern for slenderness from about 1900 onward as a fashion standard particularly bearing on women, helped sustain the disease. But the incidence of anorexia was not constant through the twentieth century in the Western world, raising questions about causation and about fluctuations in medical attention. By the 1970s, societal and parental concern about anorexia was widespread, sometimes working against efforts to limit children's food intake in a period when the incidence of childhood obesity was rising more rapidly than anorexia nervosa.
