According to a Dutch study of 500 women, the fatter a woman's waist is relative to her hip size, the longer it takes her to get pregnant. Whilst doctors have long known that women who are too thin or obese have more difficulties getting pregnant than women of average weight have, this finding suggests that fertility is not only affected by weight, but by how the weight is distributed. Even for normal-weight women, those of an apple-shape have a lower probability of conception that pear-shaped women. The distribution of fat may act like a chemical signal which triggers higher levels of female hormone in pear-shaped women.
The Encyclopedia of World Problems and Human Potential is a unique, experimental research work of the Union of International Associations. It is currently published as a searchable online platform with profiles of world problems, action strategies, and human values that are interlinked in novel and innovative ways. These connections are based on a range of relationships such as broader and narrower scope, aggravation, relatedness and more. By concentrating on these links and relationships, the Encyclopedia is uniquely positioned to bring focus to the complex and expansive sphere of global issues and their interconnected nature.
The initial content for the Encyclopedia was seeded from UIA’s Yearbook of International Organizations. UIA’s decades of collected data on the enormous variety of association life provided a broad initial perspective on the myriad problems of humanity. Recognizing that international associations are generally confronting world problems and developing action strategies based on particular values, the initial content was based on the descriptions, aims, titles and profiles of international associations.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
