BMJ Open – Abortion legislation, maternal healthcare, fertility, female literacy, sanitation, violence against women and maternal deaths: a natural experiment in 32 Mexican states

“Although less permissive states exhibited consistently lower maternal mortality rates, this finding was not explained by abortion legislation itself. Rather, these differences were explained by other independent factors, which appeared to have a more favourable distribution in these states.”

PLOS ONE -Women’s Education Level, Maternal Health Facilities, Abortion Legislation and Maternal Deaths: A Natural Experiment in Chile from 1957 to 2007

“Increasing education level appears to favourably impact the downward trend in the MMR, modulating other key factors such as access and utilization of maternal health facilities, changes in women’s reproductive behaviour and improvements of the sanitary system.”
Koch E, Thorp J, Bravo M, Gatica S, Romero CX, Aguilera H, Ahlers I (2012)

Journal of Epidemiology & Community Health – A landmark for popperian epidemiology: refutation of the randomised Aldactone evaluation study

“This paper presents two studies with contradictory results that are in a synchronic relation, forming a complete logical analysis unit: one hypothesis corroborated experimentally in a RCT confronted with a populational reality of an observational study in which its predictions are questioned.”

Public Health – Women’s education level, contraceptive use and maternal mortality estimates.

“Finally, it is important to remark that when official records of maternal deaths and live births are reliable and readily available, these should be preferred over indirect estimates of MMR.”

Journal of Epidemiology & Community Health – Impact of parity on anthropometric measures of obesity controlling by multiple confounders: a cross-sectional study in Chilean women

“Parity modestly influences BMI, but does not seem to be related to WC, WHR and WHtR after controlling by confounders. Parity can increase adiposity but not necessarily following an abdominal pattern.”

International Journal of Women’s Health – Fundamental discrepancies in abortion estimates and abortion-related mortality: A reevaluation of recent studies in Mexico with special reference to the International Classification of Diseases

“Currently, approximately 98% of maternal deaths in Mexico are related to causes other than induced abortion, such as hemorrhage, hypertension and eclampsia, indirect causes, and other pathological conditions… Rather, maternal health in Mexico would greatly benefit from increasing access to emergency and specialized obstetric care.“

Public Health – Impact of education, income and chronic disease risk factors on mortality of adults: does ‘a pauper-rich paradox’ exist in Latin American societies?

 

“In  this  prospective  cohort  study  conducted  in  a  middle-income  Latin  American country,  the  protective  effect  of education   was   not   related   to   income,   and   it   was   not completely explained by the effects of adverse biological and behavioural chronic  disease  risk  factors  detected  in  adult life  and  consistently  associated  with all-cause  mortality.”

Annals of Epidemiology – Early Life and Adult Socioeconomic Influences on Mortality Risk: Preliminary Report of a ‘Pauper Rich’ Paradox in a Chilean Adult Cohort

“These findings suggest a ‘pauper rich’ paradox in transitioning Latin American economies. Income level does not seem sufficient to improve survival in cohorts exposed to adverse early life influences reflected by education and height.”
