Famine has the potential to target frail individuals who are at greater risk of mortality than their peers. Although children have been at elevated risk of mortality during recent famines, little is known about the risks posed to children during the medieval period. This study uses burials from the St. Mary Spital cemetery (SRP98), London (c. 1120-1540) to examine the relationships among non-adult age at death, burial type (attritional or famine), and four skeletal lesions (porotic hyperostosis, cribra orbitalia, linear enamel hypoplasia [LEH], and periosteal new bone formation)...

John R Speakman
Human obesity has a large genetic component, yet has many serious negative consequences. How this state of affairs has evolved has generated wide debate. The thrifty gene hypothesis was the first attempt to explain obesity as a consequence of adaptive responses to an ancient environment that in modern society become disadvantageous. The idea is that genes (or more precisely, alleles) predisposing to obesity may have been selected for by repeated exposure to famines. However, this idea has many flaws: for instance, selection of the supposed magnitude over the duration of human evolution would fix any thrifty alleles (famines kill the old and young, not the obese) and there is no evidence that hunter-gatherer populations become obese between famines...

BACKGROUND: Schizophrenia is a common major mental disorder and prenatal nutritional deficiency may increase its risk. We aimed to investigate long-term impact of prenatal exposure to malnutrition on risk of schizophrenia in adulthood using the Chinese famine of 1959-1961 as a natural experiment. METHODS: We obtained data from the Second National Sample Survey on Disability implemented in 31 provinces in 2006, and restricted our analysis to 387,093 individuals born from 1956 to 1965...

BACKGROUND: Some studies have shown that famine in early life may influence T2D. The majority of studies on this topic have revealed an association between famine exposure in early life and T2D in adulthood. However, several studies on the Great Chinese Famine were not conducted nationwide. Because the severity of the Great Chinese Famine varied in different regions, the results of regional studies were usually limited. METHODS: We included 7262 participants who were born between October 1, 1949, and July 1, 1966 who were participants in baseline data collection for CHARLS in 2011...

BACKGROUND: Previous epidemiologic studies have reported famine exposure during early life association with overweight or obesity in adulthood, but a consistent perspective has not been established to date. PURPOSE: To determine, by conducting a systematic review and meta-analysis, whether exposure to famine could increase body mass index (BMI) in adult or not, and assess the association between famine exposure and the risk of overweight or obesity. METHODS: Published articles were systematically searched (until August, 2017) from PubMed, ScienceDirect, Cochrane, and China National Knowledge Infrastructure...

We aimed to investigate whether exposure to the Chinese famine (1959-1961) in early life was associated with depression in adulthood. We included 17,505 participants from the China health and retirement longitudinal study (CHARLS). Participants were classified into indirect and direct exposure groups. And the directly exposure groups including prenatal, childhood, adolescence/adult exposure groups. Depression was diagnosed by Center for Epidemiological Studies Depression Scale-10 (CES-D) score. Multivariate logistic regression model was used to calculate the odd ratios (ORs) and 95% confidence intervals (CIs) of depression...

Although it is assumed that epigenetic mechanisms, such as changes in DNA methylation (DNAm), underlie the relationship between adverse intrauterine conditions and adult metabolic health, evidence from human studies remains scarce. Therefore, we evaluated whether DNAm in whole blood mediated the association between prenatal famine exposure and metabolic health in 422 individuals exposed to famine in utero and 463 (sibling) controls. We implemented a two-step analysis, namely, a genome-wide exploration across 342,596 cytosine-phosphate-guanine dinucleotides (CpGs) for potential mediators of the association between prenatal famine exposure and adult body mass index (BMI), serum triglycerides (TG), or glucose concentrations, which was followed by formal mediation analysis...

OBJECTIVE: Chronic kidney disease (CKD) is an increasing contributor to the global disease burden. Previous findings indicated that exposure to famine in early life was associated with various metabolic diseases and urinary protein levels. We aimed to assess whether the exposure to China's Great Famine 1959-1962 during fetal or childhood period was associated with glomerular filtration rate (GFR) and risk of CKD (eGFR<60 mL/min per 1.73 m2 ) in adulthood. MATERIALS AND METHODS: SPECT-China was a population-based observational study in 2014-2015...

In a 54 m3 large-scale penicillin fermentor, the cells experience substrate gradient cycles at the timescales of global mixing time about 20-40 s. Here, we used an intermittent feeding regime (IFR) and a two-compartment reactor (TCR) to mimic these substrate gradients at laboratory-scale continuous cultures. The IFR was applied to simulate substrate dynamics experienced by the cells at full scale at timescales of tens of seconds to minutes (30 s, 3 min and 6 min), while the TCR was designed to simulate substrate gradients at an applied mean residence time (τc) of 6 min...

PURPOSE: Early life exposure to famine may affect the susceptibility to metabolic disorders including dyslipidemia. However, few studies explored the association between them in Chinese population. We aimed to evaluate the association between Chinese famine (1959-1961) exposure during early life and the risk of dyslipidemia in adulthood. METHODS: The study performed a historic cohort study and data were from China Health and Nutrition Survey conducted in 2009. A total of 4843 subjects born between 1941 and 1966 were categorized into fetal-infant exposed group (N = 433), childhood exposed group (N = 2132), adolescence exposed group (N = 1140), and unexposed group (N = 1138), respectively...

To enrich polyhydroxyalkanoate (PHA) producing microbial communities, generally, a feast-famine regime is applied. Here we investigated the impact of continuous substrate feeding on the enrichment of PHA-producing bacteria in two sequencing batch reactors (SBRs). In the first reactor, the substrate (acetate) was dosed continuously and Zoogloea sp. was enriched. The culture accumulated PHA upon exposure to excess carbon, but the PHA production rate and storage capacity (53 wt.%) were one-fifth of that observed for enrichment cultures in a standard, pulse-fed SBR dominated by the PHA producer Plasticicumulans acidivorans...

BACKGROUND: The association of malnutrition in early life with breast cancer risk has been studied in Europe by investigating survivors of the Dutch Hunger Winter Famine, but not in China. We evaluated the effect of exposure to the 1959-1961 Great Leap Forward famine on subsequent breast cancer risk in Chinese women. METHODS: A total of 59,060 women born in 1955~1966 were recruited from Minhang district, Shanghai, China, during the period 2008 to 2012. A baseline survey was conducted to collect demographic characteristics and known risk factors for breast cancer...

When the follicle reserve, which is developed solely during the fetal period, is depleted, women enter menopause. Intrauterine and childhood adverse conditions might affect the ovarian capacity by influencing follicle production in the first trimester, limiting the initial follicle pool or mediate an accelerated follicular loss thereafter. To investigate if adverse early life influences result in younger age at menopause, the following online databases were systematically searched: PubMed, EMBASE, CINHAL (EBSCO) and Cochrane library (Wiley) up to 1 January 2017...

Background: Prenatal exposure to famine and adulthood obesity have been independently related to the risk of type 2 diabetes; however, little is known about the joint effects of these risk factors at different stages of life on adulthood diabetes risk. Methods: The analysis included 88 830 participants of the China Kadoorie Biobank, who were born around the time of the Chinese Great Famine and without diabetes, cardiovascular diseases, or cancer at baseline. We defined famine exposure subgroups as nonexposed (born between 1 October 1962 and 30 September 964), fetal-exposed (born between 1 October 1959 and 30 September 1961) and early-childhood exposed (born between 1 October 1956 and 30 September 1958)...

OBJECTIVES: Maternal malnutrition during pregnancy may have long-lasting effects on offspring's mental health. We investigate the effect of prenatal exposure to the Dutch famine (mid November 1944 to late April 1945) on mental health in later mid-life. METHODS: Data are from the Netherlands Kinship Panel Study (n = 642). We use difference-in-difference analyses to compare mental health in later midlife (measured with the MHI-5 index) across three cohorts ('pre-famine cohort', 'famine cohort', 'post-famine cohort') and across two regions (famine affected cities vs...
