A study done by the University ofMichigan School of Public Health revealed particulars that seem to hold true for the general population. Infantsare the most cold-ridden group, averaging more than six colds in their first year. Boys have more colds thangirls up to the age of three. After the age of three, girls are more susceptible than boys, and teenage girlsaverage three colds a year to boys' two.The general incidence of colds continues to decline into maturity. Elderly people who are in good healthhave as few as one or two colds annually. One exception is found among people in their twenties, especiallywomen, who show a rise in cold infections, because people in this age group are most likely to have youngchildren. Adults who delay having children until their thirties and forties experience the same sudden increasein cold infections.The study also found that economics plays an important role. As income increases, the frequency at which coldsare reported in the family decreases. Families with the lowest income suffer about a third more colds than familiesat the lower end. Lower income generally forces people to live in more crammed quarters than those typicallyoccupied by wealthier people, and crowding increases the opportunities for the cold virus to travel from person toperson. Low income may also adversely influence diet. The degree to which poor nutrition affects susceptibility tocolds is not yet clearly established, but an inadequate diet is suspected of lowering resistance generally.
