^Lets see. We forced most of Africa to become Christian and then the pope banned contraception. We made them so poor by stealing their resources and destabilising their countries that they had (and some still have) no practical access to health care. So yes. Yes we did.
(that applies to all colonial powers, by the way, not just the British, in the interest of fairness).^
There is a slight problem with your comment. You see, Britain stopped being catholic and following the Pope two centuries before all that colonisation went on. By the time the British got to Africa, Anglican Christianity encouraged contraception. However, the Muslim Sassanid through Ottoman Empires that conquered and colonised almost half of Africa did not allow contraception or women’s rights for that matter.
